This is my second trial round of lyrica. I am on 400 mgs. as before with no side effects. I don't even know I am taking it. I have a high tolerance for most drugs and thus none really work for me. I think this time they will increas the dosage to maybe 700 to see if I get any relief. Now I am also dealing with severe TMJ as well as fibro and RSD. Taking NSAIDS for that - worthless so far. Severe TMJ, ear, neck shoulder pain, difficulty, painful swallowing. Wish I knew what to do about that.
My pharmacist said she sees people at high doses of lyrica and usually problems are more associated with dropping things, coordination, etc. Didn't mention heart problems.
Good luck - maybe the side effects will subside after using it a while. So the phar. tells me about other drugs with side effects.
