I was on Seroguel for about 1 year for sleep , taking 50 mg before sleep and by experience i gained about 80 pounds in a year because about 40 min after taking it you want to eat everything in the fridge and especially sugar then feel like a zombie and you have no choice to fall asleep . it was the craziest medications i ever took before .. but it does work for sleep thats for sure but with the side effect eating alot .. never took it for anything else tho .. good luck !
