"i have been taking belviq for 1 month, but i&#039;m going to stop because the side effects are too much.  the first week i experienced extreme dizziness, fatigue and muscle soreness.  i powered through and the dizziness finally went away.  however, the extreme fatigue and muscle soreness was too much.  i tried only one pill a day, but it didn&#039;t help the side effects.  i stopped taking belviq three days ago and the muscle soreness is completely gone and the fatigue is better.  i was so tired i couldn&#039;t even work a full day and didn&#039;t have the energy to hardly walk.  however, it was effective at weight loss.  i lost 4% of my body weight the first month."
