Hi there!!
I have always had very little appetite but since I have been on Remeron I've started eating bigger quantities at regular intervals. Although the cravings stopped after about 2 weeks I maintained my eating habits by force. I have always been quite skinny and is very impressed with the 3 Kg I have picked up since starting Remeron.
Remeron however makes you pick up weight because you get cravings for sweet things etc. It only lasts a while though and then disappear. You can control it if you want to but in my case I am trying to squeeze the most out of the cravings!
