Wellbutrin and upping

Hi I have been taking wellbutrin for over a year and I have had lack of concentration and memory loss so i went to my psycologist and he is upping my dosage of wellbutrin he said it will help with my lack of concentration and memory loss now I am reading this forumn and everybody is saying it is the wellbutrin that is causing these sideeffects. I have beent aking 100mg 1 a day now he wants me to take 150 mg 2 aday does anyone have the experience of going to a higher dose and it helping with their memory loss and concentration problems please email me at ****** with wellbutrin in the subject column thanks for your help.

I have been on Wellbutrin xl 150 for about 8 months. I also take 5 mg Lexapro daily, but am weaning off. I was recently upped to 300, about 1 month ago, since I want to eliminate the Lexapro completely. I have noticed I sometimes stutter or cant get my thoughts out fast enough! I am a nurse and work in the ER in a very fast paced environment. I thought it was just me, and I am worried maybe it is something else, but has anyone experienced this? I noticed it only after upping my dose??? also I am very concerned about the seizure statistics.. 1 in 1000 or 1 in 4000 people have seizures on Wellbutrin???? I never knew this, has anyone had a seizure from this? I am very worried!!!!!
