Hi Denny:Yes, there are days when I can't add 2+2 then there are other days when the mind is sharp. Can't figure it out, but I know it's the fibro fog. On the bad days I try not to fight it, do the best you can and don't be too hard on yourself. For me it usually passes after a few days. Mind you even on my good days I still find the computer confusing. Hang in there Denny.
