Remeron and paranoia

I began 15mg of Remeron per day about 1 month ago. At first, it was wonderful. I slept better than I had in years and my depression was reduced greatly. I felt hope for the first time in ages. However, about a week into it, I started to become aggitated VERY easily. I would get angry at anything. This has not subsided at all...in fact, it's worse. Now I wake in the middle of the night with my mind racing and either in a rage or STARVING. I eat a lot. It's nice to have my appetite back, but I crave sweets too much. I can accept that symptom if it wasn't for the rage and inability to stop my mind from switching between utter numbness to anger. I'm going to give it longer, in the hopes that it brings me back to where I was when I started taking it. If this keeps up though, I'll be in trouble.
