"i have been taking contrave for 3 days and so far the only side effect i have experienced is a headache motrin takes care of it.  what is amazing to me is that prior to taking i had insomnia and only slept 3-4 hours a night, now uninterrupted sleep and i sleep for 8-9 hours. i will weigh myself each week and report back but for now seems to be working fine 1 pill in the am and 1 pill late afternoon."
