Wellbutrin and urination

I've been taking 30mg of XL for about 2 years. This is an increase of 150mg for about a year prior. Memory loss is the worst! I often go to do something and before I actually do it a minute later, forget what it was I was going to do. I have a very hard time concentrating. I have a job where I have to be mentally fit, and have been going crazy because I haven't been able to concentrate enough to figure out the simplest things. I am losing hair bad, but not sure if I can attribute it to Wellbutrin. I sweat constantly. I wake up in a puddle of sweat and have to turn my pillow repeatedly during the night to find a dry patch. I also sem to urinate a lot more than anyone else. I am up 1 or 2 times every night to use the bathroom. As for keeping me out of depression, it's worked well, but seems to be diminishing. I am feeling more and more depressed lately. My work and relationships are suffering due to my forgetfulness and I am irritable, mostly due to being upset with myself for not being able to concentrate and figure out what should be simple tasks.

I have not found a lot of information about these symptoms online except for this site. Only little blurbs here and there. After reading this, I think it's time to quit and try something else. Does anyone know if the hair grows back and memory comes back or do they just not get any worse after stopping???
