Mirtazapine
"Have been taking this for near on 2 months. Firstly 15mg which helps me sleep, psychiatrist upped the dose to 30mg which keeps me awake. I have a very high metabolism and have been between 8 and 8 and a half stone for as long as I can remember. I have gained 3 stone and am now near on 11 stone and can never feed my appetite. I am constantly hungry and people keep asking if I'm pregnant as my stomach looks bigger than my friend who is 26 weeks gone! would recommend for sleep but not if you don't want to gain a ton of weight!"
