That’s true in some cases But people react differently to medications, to which Im sure you already know. There are a plethora of side effects from hypnotics like ambien but ive been pretty fortunate in that it only makes me sleepy with no side effects. Also, when you do sleep, do you wake up a lot or feel like youve gotten absolutely no rest the next morning? Reason I ask is that it could be something like sleep apnea...occurs more frequently in ppl that are overweight. Not saying you are...just sayin. Sucky part is that sleep studies are pretty expensive and insurances only cover a portion of them, even if they cover anything at all. Not getting enough sleep is a terrible feeling.
