Wow, thanks for replying. Yes, I eliminated NutraSweet and I noticed a big improvement.
I’d say it was coincidence but the few times I have tried it thinking maybe it was coincidence I ended up with migraines and muscle spasms so now I am convinced. My husband has not really found anything to replace it since NutraSweet or sucralose are the main sweeteners in many commercial products for diabetics but he has changed his diet to reduce the amount of artificially sweetened items. This has greatly helped his memory. In fact lately he’s remembered things that I had forgotten. What a relief!
