Yes I have experienced dizziness and muscle aches when I was coming off. It almost felt like I had the flu. Its best to come off them really slow and gradual. I always have to go back on mine but I think most people don't.
well my sister got addicted...had to be sent to rehab for help but it was really painful...the way they beg for it and the way they curse you,me as a brother was in teras...its heartbreaking.
