Well i'm new here and any info would be greatly appreciated. I've had panic attacks before about 11 years ago and I was on effexor for about a year and then stopped. My doctor put me on xanax. The xanax has done me well for the past 2 years. The bad thing is my doctor has retired and I had to find a new gp. She doesn't prescribe xanax. She tried me on effexor 37.5 mg an that made it worse from day one. The attacks were severe.I hadn't had any in quite a few years till then. She took me off the effexor and put me on celexa. I took it for 5 days and with in that time I have lost 18 lbs. the anxiety is through the roof. I stopped it 4 days ago and am still taking the xanax.It seems to be getting a little better. At least now I can eat a little. I have an appointment with psych on the 18th.Still having panic symptoms but I'm wondering if some of this is from withdrawls from the celexa.I pray someone on here has some words of encouragment.
