Sense of loss symptoms and conditions

Googled and found this site. Could not believe all that I read! I've been taking Lamictal for several years for Bi-Polar disorder. I also have GAD for which I control with another drug BUT...I guess it's been so long since I began taking Lamictal that I had forgotten, or did I ever even know, the side effects of it. First if all, the memory loss is incredible! Not being able to complete a sentence...never able to find a "word" that should be so simple to remember...going somewhere and within 2 seconds, forgetting what in the world I'm doing or where I'm going...happened today TWICE!
And to top it all off, my eyes are so bad...I didn't even attribute the L to this until I came to this site but it makes PERFECT sense! I feel such a sense of loss in my eyesight that it has begun to really scare me. I have not been to eye doc yet but plan too.
Also, someone mentioned in here that they feel the med just wears off before next dosage and that is exactly what I've been telling my doctor so at first, we just upped the dosage until I was on 450mg a day but even the, it still was not working. SO...now I'm decreasing and the doc added Depakote Er 250mg. But doc says I have to be almost completely off L to get fully on D. So...feel like crap a lot of the time!!
I'm like someone else on here who said, "just start fresh" and that is what I'd like to do but how do you go "cold turkey"? I know it isn't good! Even decreasing this L for the last several months has been hell!
I have been on a roller coaster of meds for 10 yrs. Have yet to find the "combo" that works! Sometimes I wonder if the diagnosis of BP was/is even correct.
Another person in here said he feels like he may have some side effects of OCD and I feel that way too. Nothing major but...enough for me to notice.
Damned either way, right?
One thing I DO KNOW is that I cannot take this eye problem anymore and now that I know my memory and all that other stuff has to do with L, I'm getting off it no matter what! I'm calling my doc tomorrow and we HAVE TO MAKE A PLAN!!!!!!!
I'm only 42 but my memory is that of an 80-yr old (except for my grandmother who died at 96 and could remember details of when she was 4 yrs old...lol) I guess it's good I can kinda laugh at all this but I DEF know it is not funny!!!
Anybody out there with insight to diff. meds...combo of meds?? I really am worn out!!
Right now, I am down to 375 mg of L and this has taken me several months now to decrease from 450mg...don't see the D working that well yet but it's only 250mg so...
I really am worn out!! My anxiety shoots through the roof bc of all of this! Esp. when I feel the L wearing off around 5p or so...
I'm game for any advice ( I did see where the one woman talked about changing the time you take this in the morning but that won't work for me)
Thanks!!
