The drug name in the states is Remeron. I edited you subject so the others might see it. You might get a few more answers with that

I took it one time, and only one time. About 10 min. after I took it I became "drunk" staggered to bed and slept for 12 hrs., got up for work, struggled to stay awake, came home and went back to bed. Slept another 12 hrs. Scared me since I was an insomniac. My Dr. wanted me to try and give it time. He really thought it would be wonderful for my problems, but I couldn't take it and work and had a new job so really wasn't able to give it a fair chance. I have heard that it can cause weight gain and is also used for that purpose with some people who need to gain a bit.
