I have been on 150mg of nefazadone for years and 6 months ago my doctor suggested increasing my dose to about 300 in 50mg increments. I went up to 200 and this helped incredibly. Went from weekly panic attacks and severe anxiety to the occasional adrenaline rush but not a full blown attack. When I tried to go up again to 250 I felt like a zombie and couldn't handle it. It has been 6 months and I still have episodic attacks and anxiety So I went to see my doctor. He suggested trying to up it again. Today was my first day on 250mg and I felt really out of it. I hate that feeling but wanted to know if anyone else has had the same experience and if so how long should I give it to make it a fair try? Thanks so much.
