Lex symptoms and conditions

I have been on generic Wellbutrin for almost two weeks and have not gotten a rash but have noticed that my anxiety has gone up, especially at night. I already have anxiety about not sleeping and normally will take benadryl or lunesta to help that. I also feel like I have this surge of anger, that I am not sure where it came from. Has anyone else had this? I talked to my doctor yesterday and he said to follow up on Friday and see. I am switching from lexapro to wellbutrin because of massive weight gain and to help me quit smoking. Any advice would be grateful, I can deal with it if I know its going to pass shortly!!

I have been on Lexapro for a few years now but just until recently have I experienced these side effects that I thought was something serious. But after reading all these comments I feel reassured that its caused from the Lexapro.Head rushes that make me dizzy, and making me sick to my stomach(causing major anxiety) . Another term I have read it head zaps, also true. Hot flashes one time while at work and Im only 30 years old. Major hunger all the time. I rally think my coworkers think Im crazy but not knowing what is making you feel crazy will cause you to panic. My husband has always told me that antidepressants were bad but haven't really notices until now. Im going to try and wein myself off of Lexapro and replace it with exercise. Has anyone else tried to do this?
