I have been taking citalopram now for 5 and half weeks I started at 10mg for a month then 20mg up to the 5 and half weeks. I went into docs this afternoon very near the floor, also unreality feeling was very strong, Doc said well they seem to not be working so you can try venlafaxine 37.5 in the morning and again at night. I said so when do I start? I need to tamper off citalopram first and can you tell me how I go about that, she said no it does not matter just start venlafaxine tonight, I said but they are not from the same family, she still said just drop citalopram just like that, I also showed her the lump on my jaw line, she said gum infection or cyst , they gave me antibiotics for this over the phone yesterday , but as I was there I thought I would show her. I feel very ill today anxiety is awful. Whywhy please don't worry about that if you can.
