What you describe might be Geodon withdrawal, indeed. Geodon was the most difficult medication of all for me to be weaned off of and some of my withdrawal symptoms included the ones you mentioned. Actually, any Geodon modifications were always an adjustment for me. I found it more so than any other antipsychotic that I ever took, and I've been on a total of 10 different ones over the years (not including moodstabilizers or other categories). With Geodon, and even others, consistency over time was key to tolerance and ultimately stability. I took Geodon for about 8 years. I did best on it taking it 80 mg in the morning and 80 mg in the evening (160 mg per day), along with other bipolar meds. It was side effect friendly up until 6 years in, when I developed akathisia.

May I ask exactly how much Geodon your psychiatrist has prescribed? And how he wants you to take it? [In other words, for example, 80 mg in the morning and 80 mg in the evening.] I assume that is not an "as needed" prn medication, like perhaps your benzo is. Correct me if I'm wrong.
