This is a bit crazy but I just found out I'm allergic to Aspartame after over a year of my feet and ankles retaining fluid in them and saw numerous different Dr's and not one of them pegged this. I'm type 2 Diabetic and have used Splenda now for the longest time in my coffee which doesn't have any Aspartame in it. However I was drinking diet Coke for a long time and really enjoyed my diet Coke for some time now. Well after taking everything into consideration I finally narrowed it down to maybe it was the diet Coke. I stopped drinking the Diet Coke and within 4 days almost all the fluid is gone from my feet, ankles and just from the knees down and my legs are back to normal now a week later. It's amazing this was it, I just wanted to report this just in case anyone else may be having this problem. I was starting to think it might be vaping and I would have to quit. If any vendors happen to be using Aspartame for a sweetener I really wished they would somehow disclose this on there juice label, I mostly DIY all my own juice but I would hate to buy a juice that has this Aspartame in it on the rare occasion I buy a bottle of juice. This Aspartame is like poison to my body anybody that may be having any fluid retention I would double check to see if your using this Aspartame in any drinks or food products and quit using it and see what happens.
