"i started belviq after first losing a significant amount on weight watchers, so progress was sort of slow for me. i lost about a half a pound a week for the three months i was on it, but my motivation level was low. the problem for me came when i tried to stop taking it.  i had the symptoms of antidepressant discontinuation syndrome pretty bad. these included lightheadedness, dizziness, tingly hands and feet, and blurry vision. this all scared me very much - i thought i was going to have a stroke. i even had what felt like an electric shock shoot through different parts of my body a few times.  i was really relieved to find out that this is a fairly common condition and only lasts 2-3 weeks, but it was pretty uncomfortable."
