Hi everyone! My name is Crystal. It's been a while since I was on this board. About a year ago I tried guaifenesin for a few months. I was feeling so crappy, as I know you are supposed to, but I gave up because at that time I found Lyrica and it has helped tremendously. I'm thinking of trying it again because I've seen that so many people have had success on it. I was wondering if I should take the fast-acting or the long-acting. Which one do any of you have better results with? Thanks!
