Thanks Batch and Sean McE. I appreciate your comments.
An update for anyone who’s interested and a bit more detail about things!
I’ve reduced my Verapamil to 180mg a day from 240mg previous. My usual range is 240mg to 480mg. I refuse to go over 480mg due to it making me feel like a zombie, and just put up with attacks and feel sorry for myself when things get bad. I dropped to 180mg a day on Monday. Since then I’ve had no attacks or shadows. I did a beer test on Saturday evening (well, a dry white wine test) and nothing happened. Therefore, I carried on, had a few more and still no shadows or attacks for the rest of the evening. I’m now thinking of dropping to 120mg in a few days time. My verapamil is slow release and I take it all in the morning.
So, just to clarify what I’m doing at the moment, it is as follows . . . .
- KETO/LCHF diet, less than 50g of carbs a day. Probably average around 30g. ZERO SUGAR!
- Three meals a day (breakfast, lunch, evening meal).
- 600mg NAC tablet with breakfast.
- A slightly ‘slimmed down’ version of the D3 regime with breakfast.
- Trying to consume broccoli sprouts everyday with lunch or dinner, when possible. I grow these at home. It's very cheap and easy!
The broccoli sprouts and NAC are to help maximise glutathione production along with the keto diet. My slightly more detailed working theory, which is of course most probably wrong, is that the keto diet works so well for Clusters and Migraines because of its general anti inflammatory effect and/or the increased glutathione levels dealing with ‘histamine issues’ from mast cells. That said, they could be considered to be interlinked and the same process/outcome. Now for the broccoli! The sulforaphane released from chewing the broccoli sprouts drives the Nrf2 pathway. This results in even more glutathione production along with the NAC, which is the limiting factor in glutathione production in the body. Now, all of this could be nonsense. However, as long as it’s working for me and possibl of help to others, I’m more than happy to be completely wrong!

Note for Sean McE:
I hope you do not mind me commenting on what you said about not being able to do keto. You are more than welcome to disagree and tell me to mind my own business. In my defence, I'm very keen on the diet and I’ve studied it inside out. Including its effects on general health, clusters, migraines, auto-immune disease, other illnesses and quite a lot on it's effects on sporting performance. I could literally bore you to death about it. So, apologies if I do so. I’m certainly not trying to be a ‘know it all’, I'm just enthusiastic!

It doesn’t matter what level of bodyfat you have for keto. I reckon my BF% is now around 8-9% and I’ve never had more energy and I never dip. There are many extreme marathon runners (running 100+ mile races) who have less body fat than both of us, that excel on keto/LCHF diets (it’s becoming the diet of choice for these types of athletes). Even the slimmest and smallest of long-distance runners have 100’s of thousands of calories stored in fat. You cannot run out of energy from stored fat, you’d have to be significantly malnourished. Now, the human body can be powered by ketones or glucose (glycogen). Note: Please don’t take offence with this next bit! I strongly suspect that the reason you run out of steam by midday is because you have no fat adaption and rely almost exclusively on glucose (most of the westernised population is the same, as was I). Therefore, you use the approximately 2000 calories of glycogen (that your body can store in the muscles and liver) very quickly, and because you have lost your fat burning ability, you start to crash because you run out of energy. The irony is, that the more frequently you eat carbohydrate the more reliant you become on it, as your body rarely gets the chance to burn fat. Crashing after going hours without complex carbs or sugar is a classic sign of this. It isn’t because you are lean. I am a cyclist, I used to crash on and off the bike if I didn’t eat carbs every two or three hours. I lived on carbs. Since going through the adaption process when you start keto (it’s called the ‘keto flu’ and can be a rough few days) and to this day, I have become more and more ‘fat adapted. It wasn’t long after starting keto that I was able to ride 50+miles on water only and noticed I wasn’t having dips in energy throughout the day/evening any more. If I had the leg strength endurance (which I don't at the moment), I could easily do 100+ miles without any energy bars, drinks or snacks tomorrow. It’s just a question of becoming more ‘fat adapted’ and less reliant on sugar/carbs/glucose etc. I’m the end I guess what I’m trying to say is don’t rule the diet out in the future if your clusters get bad enough. I firmly believe that if the diet works, it’s a far better option than the drugs we all chuck down our throats every day. There are many other benefits of the diet too, I’m my experience and honest opinion. All the best Sean.
Sorry for waffling on!
Kind regards
