I have been taking lyrica for around 7 months now. My pysch tapered me up slowly from 25 to 200 x 2. It really helped the GAD and panic attacks although made my hair brittle and my eyes feel a bit rolly.
Foolishly I have tried twice to reduce and come off the lyrica and each time have plunged into the darkest depression and physical pain with tremors and exhaustion etc. I am now back on to 100 x 2 per day and see how that goes.
It is considered a bit of a miracle drug for anxiety in my area and I would not disagree, but beware the withdrawal symptoms.
