Sleepy, I'm a big fan of Pregabilin. It was sold to me as Lyrica in London. A few comments though
1. I can only tolerate it at around 25mg a day and only in batches i.e. a couple of days, then stop. All my attempts to work up to large doses/more days failed miserably. Each time I got "over hyped", developed sinus infections and then crashed with ME symptoms worsening (weakness, sort throat, glands, flu feeling etc)
2. I don't have anxiety so don't know how well it works for that sorry
3. It helped control nerve pain very well indeed for me. For the post exertional ME muscle type pain it did nothing
I know that they sound like massive problems but after about 6 years of nerve pain it was an enormous relief to find something that actually did work - even if I have to pulse it and take breaks. The FM doctor I saw said in a small number of cases people are using it like I do. He didn't think that it would work to control pain in the way I am taking it but he has now seen a few patients who are very sensitive to drugs and the same.
