After having successfully tapered off cymbalta (caused weight gain, high bp, brain fog) that was prescribed for Ibs, anxiety and some depressive symptoms, I’ve started up Prozac. My doc put me on 10mg and I’m on day 12 now. Initially increased anxiety, lurking panick attacks, after a couple of days I wanted to cry, especially in the mornings. Later in the day that would subside. Yesterday some of that suddenly lifted and continued until the morning. Now anxiety has come back.
Is it common to have these ups and downs? How long do they last? Doc wants to wait until 4 weeks to either increase dose or switch to Lexapro.

An advice or experience is welcome, thx!
