Lynn, have you considered looking into a prescription for a mild stimulant? I've just started on a VERY low dose (5 mg.) of Adderal - my neuropsychologist recommended it after my latest neuro-psych tests were evaluated.

So far, I can tell a distinct difference in my ability to concentrate and process new information quickly, (such as driving in an unfamiliar area of town and needing to visualize alternate routes from a map in my head - that was impossible just a few weeks ago). It also seems to alleviate some of my fatigue.

He feels that any of the ADHD/ADD drugs help MS patients with cognitive issues and many of them see an improvement with fatigue, also, but only if taking them daily. Due to side effects with my heart condition, I only take mine when I have to leave the house or work on anything requiring focus and concentration, so the fatigue help is spotty for me.

If you think you might benefit from this type of therapy, you can research Adderal, Ritalin and Provigil - I'm sure there are other drugs of this type, but those are the ones he uses. Provigil is very expensive, but I'll probably want to switch to it when a generic becomes available since it has fewer heart-related side effects.

Good luck. I can't imagine having to function in a classroom setting when the "fog" descends. I admire you for soldiering through; I don't think I could do it. Kudos!
