I was taking Citalopram off and on for the last 10 years however at Xmas it stopped working even after maxing out the dose at 40mg. So my doctor switched me to Paxil CR. Started at 25mg for three weeks then up to 37.5 for a week and now 50mg. Now I understand you can up this one weekly as opposed to every other week but at what point should I feel better and not have to go up anymore?
