Hello Nerak,
Wellbutrin side effects:
agitation, headache, dry mouth, nausea, change in appetite, insomnia
Prozac side effects:
anxiety, drowsiness, headache, insomnia, diarrhea, sexual dysfunction, excessive sweating, itching, tremors
The shakiness could be due to the medication, especially if you are taking them in combination. If you are experiencing any kind of side effects at all, it is important to let your health care provider know immediately.
