I have managed to defeat most of my Autistic/Asperger's Food Issues, with a couple of glaring exceptions, however I am not the same when it comes to soda.

Over the years, there have been a number of different sodas that have been "Acceptable Fluids", and one by one every single one of them has been discontinued or had their flavors vastly changed.

The most recent thing that I've been drinking is Walmart-brand "Great Value Diet Mountain Lightning", but it looks like the grim reaper of 'not calling things Diet' has maybe finally come for it too, because it is out of stock everywhere now, and I just noticed that they are NOW selling...

Great Value Mountain Lightning Zero Sugar

That is never a good sign. Krogers soda all became not potable anymore after they switched their everything to "Zero Sugar" from Diet, so I am scared.
