Wellbutrin and estrogen

Right now I am a total mess from taking Wellbutrin, sr. I started at 150 mgs last summer. I am now up to 450mgs a day, plus 80 mgs of Prozac a day. The doc cut my Prozac dosage in half, without telling me, and for the last week, I feel like I'm going out of mind. I am going to the doc tomorrow to have a PET scan, just to make sure I don't have a brain tumor, but I am pretty sure I know what is causing all these symptoms. I don't know if dropping the Prozac dose set me off or what, but some of the symptoms I have are; the worst headache I have ever had, dry mouth, ears ringing, heart palpitations, stumbling (I fell down 5 times in the last 2 weeks, enough to send me to the ER) I feel like I have no co-ordination, I tremble and jerk uncontrollably, and I am totally brain dead. I can't remember from one day to the next what I did, or was doing. Heck, in the last few days, I can't even remeber what I did 15 minutes ago. I start something, and walk away from it, and then I think about it later, although so far I have let the sink over flow a couple of times, and let food burn. I have been married and taking care of my family for 33 years, and now I can't even get my kids', my grandkids', and the dogs' name straight! I forget a word I know that I know, and it makes me so frustrated. I have outbursts of crying, the other day I had a meltdown because I couldn't find the leftover ham bone to make soup. I talk real fast, and sometimes get the words all mixed up. I do impulsive stuff, like I maxed out the credit card during Christmas. My husband is going nuts, too, because he says it's like living with another person. Today I have felt like I could barf at any minute, my head is pounding, my heart is pounding, and I could stay awake forever, and then in an hour I'm so tired I have to take naps every day! I never took naps, since I was 5!! I had a similar experience when I was on Paxil. Prozac has worked for me since it first came on the market, but since my doc added the Wellbutrin, I just don't know. It was working fine until she cut the Prozac dose in half, so maybe that set it off, I don't know. I wish I could get off all the crap, but due to PTSD, I have to take at least the Prozac. I hope I get some answers tomorrow!
