So about 6 or 7 days ago my psychiatrist reduced my Prozac to about 40mg. I was on 60 mg for three years while on abilify and had been mostly symptom free. But 7 days ago I became hypomanic and a bit delusional, and I knew I had to call him. So he didn’t touch the abilify (I’m on 10mg) but we went from 60mg of Prozac to now 40mg…. That a 20 mg difference. At first I felt as if I was dizzy, going to faint, etc; and now it’s so difficult to sleep. I’m strangely calm though, no sign of hypomania or mania as of now. I have been sleeping but it’s very broken…. Like I’m tired but my brain is having a hard time shutting off. I did let my psychiatrist know about this and I’m taking a magnesium supplement and adding melatonin temporarily. But is it possible that a change of brain chemistry caused me a bit of insomnia? Has anybody else experienced something like this?
