Dave how long have you been DXed? That too can play apart of what we call cogfog here at NT, the stress can interfere with the neurons firing with cog issues, and if this is your first year of surprise you got MS bs, the first one to two years tend to be the toughest, adjusting and adapting, can get a bit perplexing at times.

I hope its just a stress related cogofg, but as times goes on I still see my own cogfog issues, names and what i said puff its gone in two days, things from child hood are still there and my numbers i am still good with . 3.14 should be the Pi number if my brain remembers from math class eons ago. Try to take it slow one day at a time and don't forget you have NT to help you ease and guide you in any way we all can,

wasnt it Pi times the radius told you the circumference of a circle

again welcome to NT Dave
