So this will get long-winded, because there's a lot I've been through in the last couple months. Fair warning.

To start, as of January I had been started on lithium with instructions from the neuro to take 300 mg the first week, increasing to 600 mg the second week, then 900 mg the third week if no response. No blood tests were ordered during this time. On week three, I went to work feeling shaky and unsteady on my feet. I'd been dehydrated from nausea, so I chalked it up to that. But after having lunch with coworkers, I got back to work and started having strange symptoms. My hearing was "double", like there was an echo in the room. I started to get weird shaky jerks in my body whenever someone made a loud sudden noise. Then the next thing I knew, I had blanked out while convulsing and collapsed. I think I was out only for a few seconds. Friends said it looked like a seizure.
I was taken to the ER where they ran a bunch of tests. I told them about the lithium I was on, and they took a blood test. Apparently the acceptable upper limit is 1.2 and mine was 1.7. Yikes! I spent a couple days in the hospital while they pumped me full of fluids and made sure I was okay. Lithium was discontinued.

Followed up with GP, he confirmed I should stop taking it as my body was metabolizing too well at that dose, which was so far ineffective. While in the hospital, I was also prescribed metoprolol and amlodipine for high blood pressure they discovered. Yet, when I saw my doc, my BP was 90/60. He felt the BP meds were maybe working TOO well. Yet when I got home, my BP was back up and I decided to keep taking the dose I was prescribed. They said it might also help with my headaches.
Well, this weekend I took the usual dose but woke up feeling weak, dizzy, and heart pounding. Decided to go to ER, where they discovered my BP was 80/50, pulse rate 50 bpm, and my heart rhythm was all over the map. Part of my heart had stopped working, and the rest of it was working overtime to compensate. Something about an "junctional escape rhythm". I was admitted to hospital again.
Turns out, my prescription was wrong. I was taking two times more medication than I needed. Pharmacy did not make the mistake, as I checked the written prescription with them. Someone at the hospital screwed up. Could have killed me.

Right now, I'm not on any prevents. I've failed all of the normal ones. I'm looking into the alternatives, of course. And 02 and Imitrex continue to abort, thank goodness. It's been a scary ride, and I've had quite enough of being a pharmaceutical guinea pig. It never seems to end well for me.
So thanks for reading, and sorry I've been out of touch.
