Seriously, are you taking 75 different meds? I'd be sitting down with pharmacist and try to weed out as many as possible. They are the ones who are supposed to know if what you're taking is compatible.

It seems from reading here that the lion's share of people who try Lyrica/PreGabalin can't seem to tolerate it. I switched cold turkey from GabaPentin to Lyrica. Other than ED no real side effects from Lyrica and it helps me considerably more than GabaPentin did. I don't think I could do without it now.
