Interesting to note that most neurologists and MS specialists will tell their patients to cut out artifical sweetners immediately.
I truly believe that aspartame is a poison. When I was younger I was drinking at least a 2 liter bottle of Diet Pepsi a day and I have some major mood changes every time I consumed it. My family noticed that every time I drank the stuff I would become very hyperactive and mean, almost violent. As soon as I cut out all aspartame then I went back to being my calm, laid back self. Haven’t touched the stuff in 20 years and I recommend that people stay away from it.
