I had issues with all artificial sweetener after surgery.   I tried the stevia/truvia/splenda/equal/etc and hated them all.   But after a few weeks I started tolerating Splenda.

There are tons of products made with Splenda.  Have you tried that over sugar alcohols and aspartame?

I was diabetic before surgery and sugar free candy was all I could eat, but after my RNY I can tolerate  sugar better than sugar alcohols. I had a lot of trial and error but I stay away from sugar free
