"i have tried every diet under the sun, have worked with numerous personal trainers, and although i have been faithful 85% of the time on any diet i have been on, i have never been able to lose weight at a healthy rate. i normally have to do an extreme diet to see any progress and then my body will fight tooth and nail for the weight to come back. 3 months ago, i spoke to my doctor and she recommended belviq because it has the least chance of side effects. i do have them though. for the first month, i would say headaches were pretty bad, but i would take excedrin. but the tiredness that has lasted for the entire time, though it is not debilitating, it does effect my desire to work out. i have lost steadily though, 1.5-2pds a week at 1550 cal"
