Uncontrolled anger symptoms and conditions

My 3-year old daughter just took her first and last Singulair today. Within 3 hours: crazy mood swings for no reason, uncontrolled anger, bad dreams during her nap time. I didn't recognize her. She's been on Zyrtec for 2 weeks and showed improvement with her allergies and no side effects, but for some reason I let the doctor talk me into trying Singular today. I just threw the Singular in the garbage. Back to Zyrtec tomorrow.

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!!
