question: For the past 3 weeks Ive been suffering with ongoing severe derealization and I cant shake it. I wanted to know if their are any medicines that can help with this and how long does it take for them to work? I had a severe attack like this 2 1/2 years ago and was put on wellbutrin for it and the derealization went away after about 5 to 6 weeks. I went to the doctor this past tuesday and she put me on citalopram and metoporol and she said it should work much faster than wellbutrin but it hasnt worked so far and its been 4 days.
