My dose of Citolapram was increased from 30 to 40 last Thursday. However I was put on Xanax 2 weeks ago and I was told to stop taking it on after the weekend. Now my anxiety levels have increased and feel a bit depressed, restlessness, loss of appetite and tummy disturbance since yesterday. Am I going through withdrawl symptoms of Xanax? How long will it take for the increased dose in Citolapram to kick in?
