Wellbutrin and allergist

i have been taking wellbutrin for almost 3 months to quit smoking (300mg/daily). BE VERY CAREFUL with antihistamines-i took one not long after i started the wellbutrin & felt that horrible seizure-ish feeling coming on, paranoia, racing thoughts & found out from another doc that they are not supposed to be mixed. which sucks for me, because i have suddenly become allergic to dogs & can't take any benadryl-my allergist says there is nothing that she can do until i can take it.

i asked about weaning off it (this med has me scared s*less now). i took it every other day for about 2 weeks. i haven't had it in about 4 days & i feel ok, a little psycho at times, but nothing out of the ordinary lol (i haven't been on it long at all, so i don't know if someone who's been on it for years should get off it the way i am). i just want it out of my system so i can get some relief from my allergies!!!
