I've been taking this drug for about a year and I have also tried to quit the drug with no success. The headaches, unable to walk straight, sick to my stomach is enough to make me take another pill and after taking that pill, all the symptoms go away within an hour. I had lost my husband and this is the second drug they put me on. I'm still on it and they say it helps with nightsweats, which, was also a symptom I got when trying to get off. I've also gained 30 pounds. I want off! I'm taking 150mg. How do I get off, cold turkey can't happen for me.
