"today marks the first day of my 3rd week - 2 in am, 1 pm. my appetite has yet to be affected by the medication. i still have massive hunger cravings in the afternoons the same as i always have. i am also trying to stick with weight watchers and with that prior to this medicine, i lost 6 lbs. i have yet to lose anything in the last 2 weeks. i don&#039;t work out right now. the first two days i experienced headaches - as with most new medications. i also take metformin in the morning for my pcos. only slight nausea at certain times in the afternoon before i take my next dose. other than that, i was on belviq for 3 weeks before this and same thing, no results. hopefully after i am on the full dosage, something will start to change."
