I've been suffering with this for a week and finally went to the doctor yesterday (can't move my neck or raise my right arm above my head). He prescribed Zanaflex in capsule form, which I see everywhere that it's not the same as the generic or pill form, but doesn't say exactly why. The pharmacist came out and told me that if I took this, I was to do "nothing". He said you *will not* be able to drive, you will lose motor function, it blocks signals to the brain and there is no telling how it will affect you. He said to take the first dose when I went to bed, not before. PPFFFTTT!!!! All of the medicine I take say "may cause drowsiness, don't drive or operate heavy machinery" So, I get home from the pharmacy and I take one, the dosage is two, so after about 45 minutes and not feeling anything, I take the second one. Within another 45 minutes, my speech suddenly becomes slurred, I lose control of my arms and legs and start hallucinating. Luckily I was sitting on the foot of the bed when it happened and managed, with great difficulty, to make three "seal jumps" (you know how a seal jumps out of water and onto the land?) towards the pillows at the head of the bed so I'd have something under my neck. I hovered between waking and consciousness for about 90 minutes before I was able to gain enough control of my arms to lift myself up, but still could not stand up. Scared the crap out of me. Anyone else ever used this stuff?? Oh, and it doesn't relieve the pain at all. I called my doctor, but he was off today, so just wondering if anyone else takes this stuff.
