Took this product for about 2 years. Had terrible problems with insomnia, ringing in ears, anxiety during that time. I liked the fact that I had lost about 2 sizes so I was reluctant to stop. When I did, even though I decreased the dosage very slowly, I had terrble withdrawl symptoms. Extreme hostility, agitation, up for days, suicidal thoughts (which I'd never felt before). The doctor had no idea what would help. I called Narcotics Anonymous and was told to drink lots of water, cranberry juice, walk, take hot baths and above all pray. It has been about three weeks now and the worst has passed, but my life was hell for about two of those weeks. I don't believe doctors give you the proper counseling when you get on/off these or any other meds. They are too busy writing prescritions and keeping the drug manufacturers fat and happy!
