I've been keeping my eye on my BP while taking Verapamil.

For the last 5-6 cycles I've gotten away with 160mg per day (40x4).

Now I am on 240mg while waiting for the D3 regimen to kick in (Day 10) and I'm still not getting consistent relief (2 PFDAN's then 2 days of crap).

I've been grudgingly considering upping to 280-320mg on the Verap. Took an 80mg tablet this morning (normally i was taking 40mg x 6) and checked my BP just now (2 hours later). It was 92 over 62 (11am). Normally I am 100 over 60/62 every time.

Is this move significant? Don't feel worse than I do generally on Verap which is crap.

Also, I hear people take stronger doses of Verap at night (when headaches are worse). Does anyone else with low BP to begin with have a concern about heavier nighttime doses. It's all in my head I suppose (no pun intended) but I feel like the Verap gets me so low that I don't breath sufficiently while I sleep to fight off the CH. 

Most people need around 240-360mg a day of verapamil for it to be effective, although some go to around 1000mg a day. So you're still on a relatively low dose.

It takes around 7-10 days for a dose change to become effective, so since you've just hit day 10 of the higher dose then you need to look at the relief from now on.

If verapamil isn't giving you the right level of prevention, also consider the alternatives like lithium or topomax.

I take Verapamil 80MG 4 per day for a total of 320 MG per day, lessens the severity but does not take them away. I asked doctor to UP the dosage and he strongly refuses based on strong side effects he said.

You questions should be directed to you doctor.

When BP gets as low as you report, I'd be surpised if you didn't have some negative side effects.
