I was on Celexa for 7 days total. On the third day, I had extreme anxiety, by the 5th day I was suicidal and could not collect my thoughts. I have never been this way prior. I saw my GP and he upped my dosage which made things worse. The next couple days I was having extreme tremors, nauseous, lost a lot of weight already, have not been able to eat for a week, very suicidal, wanted to commit myself. Talked, more like cried this over with my husband and we came to the conclusion it was the drug doing this. I had not been this way the week prior. I took my last pill on Sunday, its now Wednesday and I still have some effects. How long until I feel like normal and can actually eat again?
