Xanax Withdrawal

I had my surgery on the 14th (Valentine's Day; what a great day for surgery!).  I amazed myself by not being anxious that morning.  I had to stop taking all my meds the night before, and I was so out of it from the anaesthesia that I didn't take my Xanax or Prozac for several days (I was scared they would make me feel even more out of it).  Last night, I had some visitors over to check on me post-surgery.  I felt so jittery and didn't realize what was wrong with me.  I just felt wired.  One of my friends asked me if I was still taking my regular meds.  When I told him "no," he said "No wonder you're jittery.  You shouldn't just stop taking your Xanax."  I went immediately and took one, and felt better in a matter of minutes.  I had just assumed the jitteriness was from the surgery or from the steroids I was taking to control swelling.  I had no idea going off Xanax would make me feel so crazy.  But now, I've completed all the steroids, and I'm back on all my regular medications, so I feel fine again.  I still take the Xanax three times a day, and I've adjusted to it so that I don't feel "loopy" anymore (i.e. no more falling off of chairs).
