Fifth grade level symptoms and conditions

As with others on this forum, memory loss is a side effect I'm experiencing with Lamictal. In fact, it's THE only side effect. I began taking Lamictal three years ago, and have maintained a dose of 300 mg a day. My short-term memory is practically non-existent. I have to write EVERYTHING down, and sometimes that isn't even enough. I've been known to forget what I've read only minutes before. I used to pride myself on my impeccable spelling, and now I'd say I'm at a fifth-grade level. In fact, I feel like I'm about ten years old. I've been taken to task over and over by employers who are frustrated with my poor performance. I've lost one job and due to lose another any day. Sure, my mood is stabilized, but for what good if I can't even support myself? I would definitely go off this medication if there was a good chance I would get my memory back, but I haven't come across anything in my internet travels that indicate this is a possibility!
