"i started belviq monday may 2nd. i have yet to feel an results. if anything i feel like eating everything i see.. i&#039;m wanting to eat more than i did before starting it. i have read some reviews showing that the medicine took a few weeks to start working. i hope this is my case. i do feel very sleeping after i take it. it is harder for me to get up in the mornings. i feel like i am in such a deep sleep since i have started. i haven&#039;t had any headaches but have noticed dry mouth."
