"i&#039;ve been taking this medication for quite awhile, and while it worked at first, i noticed that i quickly started building up a tolerance to it. every couple of weeks, my dose is increased, and it&#039;s been very frustrating. while it does get me to sleep, it doesn&#039;t help me stay asleep. also, there has been a tremendous amount of weight gain, which i can&#039;t lose even with diet and exercise. great for short term, not for long term."
