"i have been on this medication for 16 days now and have not felt any different at all. i feel like i&#039;m still me, not any happier or sad. the only thing i&#039;ve noticed is that i use the restroom more often. i couldn&#039;t sleep well the first few nights but now i can sleep whenever and not wake up until morning. i don&#039;t know how long it would be until i start to notice any changes."
