"i started a month ago at 184lbs. i am now at four times a day dosage. side effects have been minimal. the worst has been insomnia. not full on, i still get sleep, but it is not usually a good night&#039;s rest. dry mouth in the beginning, which forced me to drink more water (a good thing). that side effect is gone. for the first 2 weeks, i really did not notice any difference and was not losing weight. after 4 weeks i weighed myself again and i was down to 173. so 11lbs. in one month with minimal exercise but a big change in diet. i also tried this medication because i heard it helped to stop smoking. unfortunately, my nicotine habit has not been effected. i am continuing with contrave and hope it continues to work. very pleased right now."
