Today is day 16 of my quit. I called the pharmacy to refill my Wellbutrin since I am down to my last pill. This medication has been working great but guess what? I am now having an alergic reachon. I cannot stop itching. I called the pharmacist and learned that about 4% of people who take it will have this reaction. I am waiting for a call from my doctor. I am now checking to see If I have any Benadryl. If not I will be running to the drug store.
