anorexia
"All my life I have struggled to gain or maintain my weight.  There are periods when I have no appetite.  Can go for days and not eat and not get hungry.  This medication has been a God send.  At first the drowsiness was almost debilitating.  After reaching my desired weight, I found that dropping the dose to 1/4 tablet per day kept it on but without the side effects.  My son suffers from the same thing and he is now on it too.  I highly recommend it to anyone wanting to gain weight."
