Cyproheptadine
"Started this medicine 2 days ago.  Slept for 14 hours straight.  Hunger just kicked in and I ate a huge sandwich and drink and I'm still hungry.  Changed dose to 1/2 of 4 mgs and got up this morning normally.  I intend to build up slowly because of the sleepiness side effects.  I intend to stay on this due to my fast metabolism and stress to get back to normal.  I think it is working!"
