Remembering names symptoms and conditions

I have been on Lamictal for Bipolar II for a little over two years now. The first side effect I really noticed was that I had zero desire to exercise anymore. I used to be pretty athletic, loved to go on hikes, now I could care less. Also, my brain is mush. I am a former honors/ Dean's list student; I had one professor in college tell me I was the only person in class who would ever be able to write professionally, and I have been trying to write the same novel for three years now. I forget how to spell words and how to formulate sentences. I can never find the right word. I forget what the plot is, what I wrote in the last chapter, so I am constantly re-reading what I wrote. I started to think that I had ADD because I couldn't focus on anything, and I couldn't remember if I had always been this way or not. Granted, I think I have always had a bit of a problem with executive functioning- organizing, prioritizing, completing tasks- but it has always been more of a problem with keeping my house clean, etc, NEVER with writing. Also, I have always been very good at remembering names, dates, events in history- the random sort of information that makes a person stellar at Trivial Pursuit- and all I can say now is, 'Uhhh... oh, man, I KNOW THIS.' Also, I am becoming incredibly antisocial, which I think probably has something to do with the fact that I no longer know how to talk. (A sidenote: I'd say chances are good that I have Asperger's; socializing has always been a challenge for me. My point here is that I'm wondering whether Lamictal is making the things I have problems with worse, ie, executive functioning, socialization..., etc. I used to be able to overcome these impairments intellectually; now that my brain doesn't function the way it used to, it's way harder to compensate.) I had a conversation with my husband the other day about all of it, whether he thought Lamictal was truly helping me. He told me that I no longer seem interested in doing anything anymore; that I am no longer sharp like I used to be; that I lack the vitality I used to have; that I no longer get excited about anything anymore. Now I know that Lamictal is a mood stabilizer, that I am on it to stabilize my moods, so obviously there are no longer going to be the highs that there once were. But now I feel so flat and dumb I just don't know. By the way, I have worked my way down to 75mg at night from 200mg. (Which is an improvement, I'll give you that- before I was scared to drive because I'd practically forget I was driving, that's how crappy my short term memory was.) Just so you know, I don't feel depressed, so it's not that my dose is too low and I'm experiencing depression. I just don't feel much of anything at all anymore.

Is anyone experiencing confusion, trouble thinking, trouble concentrating, decreased cognitive function, mental sluggishness, trouble solving problems or situations which require logical thinking and sequencing, and memory loss? Would love to hear from anyone experiencing any these symptoms and if so, how long were you on the drug.
Thanks!

I have been taking Topomax for quite some time.Tried it several years ago, the mgs were not high enough (only 25mg/day).My doctor didn't really know the prpoer dosage.It didn't help the migraines.My new doctor has me on it again.50 mgs/day.Here's the good - NO MIGRAINES! Here's the bad: Acne at 45 years old, tingling doesn't even describe my legs or face, ringing in the ears, remembering names and places just doesn't happen, I'm eating less but gaining weight quickly,& one last thing- Itchy spots that I would describe as "hot spots" if I were speaking of my dog. Still sticking with it because I don't have the migraines.I tried to slowly take myself off and the headaches came back.What choice is there?
