I want to share my experience with remeron so far. Till two months ago I couldn't stop flushing, burning etc. For almost a whole year! Literally non-stop almost and it drove me desperate. I had an IPL treatment in the beginning of 2005 that didn't went ok and triggered this extreme state: it made me extremely sensitive and flushed. Lately I've added propranolol and mirtazpine (remeron) to my regime (already using moxonidine, 0,2 mg three times a day) and it's making such a difference! I used propranolol before, with much less improvement, so I feel that most of this is due to the mirtazipine. A very knowledgeable dermatologist from London had prescribed it to me, especially for my extreme flushings. It cuts down my flushing episodes, the intensity of them and my general redness. I want to recommend it highly.
Side-effects: indeed: increased appetite and therefore some weight gain. I had a few weeks sort of a rash and itching on my face, but that has stopped lately luckily. It helps you sleep fast during the night, but gives me some vivid dreams, but that's not unpleasant.
