Wellbutrin XL and medication

I have been taking 300mg of generic wellbutrin XL for about 2 years. I recently started doing some research on side effects because I always feel dazed and out of it. It never feel like I am awake—it’s like I am in a constant fog. I consistently feel groggy, can never think of the correct words to say and have trouble concentrating on even mindless tasks. I spoke to my doctor and he said that I can go off of it; that sometimes antidepressants can have these types of effects on a person. How long will it take for the brain fog to go away? I really hope that these are symptoms from the medication and not something else because I don’t want to live like this anymore. I’ve began to taper down—I’m supposed to take 150 mg for a week and then go off of it.

I'm so sick of being dazed and confused!!

The only medication i take is Wellbutrin Xl low dosage. I don't know if this is actually FROM the Wellbutrin, but about 9 months ago, i developed urinary tract symptoms of chronic urination. I have to go to the bathroom dozens of times a day , and at night I get up 6-7 times to pee. Full bladder pees.
I do drink more water during the day, as i get dry mouth from the medication, but this is not just related to water, because if i stop drinking more water, this will still occur. I'm in good health and my doctor told me I am too young to have urinary dysfunctions that come in older age. There is nothing found by ultrasounds. I Was wondering if anyone else on WELLBUTRIN XL is experiencing this as well. Also, recently I had a sudden increase in my blood pressure. I don't have a history of this.
I am 49 yrs old, white female and in generally good health.
I would not fail to mention that Wellbutrin XL is an excellent Antidepressant, the best of any of the others i have tried over the years. I am almost fully functioning, but still working on my issues.
I actually have felt emotions that were happy and positive on a recent basis after many years of "numbness". this drug has not had any headaches, anxiety causing, that wheel spinning or disorientation those other antidepressants had for me. I had to stop taking more than 8 different antidepressants in the past.
I'm just mostly wondering about urinary dysfunction issues. Please post if you are using this and having this.

so far i took it for about two months. Yes it's an anti-depressant aid, but I was prescribed this medication to help with my smoking habits. I felt a surge of energy, and a concentration to do things, but I've also noticed that it keeps me awake. It's similar to insomnia. It's not that I can't sleep, but that I don't want to. I know that if I just lay down and go to sleep I most likely will. But other than that, I don't believe it has helped me quit smoking. It, I guess, made me feel happy? I really don't think it worked...
