I've been on Paxil 80mg a day for panic, depression, and anxiety for about 4 years. Went to the psychiatrist because I think it has ran it's course. She switched me to 20mg of Viibryd and reduced the Paxil to 60mg daily. Not having much luck at all. Severe anxiety, no appetite, lost weight, some diarrhea, tremors and shaking, dry heaves. Been on this for 10 days now. I feel really bad. Any input is greatly appreciated.
