Big one this, artificial sweeteners are very bad for Synapse XT. You may think, well if I can't have sugar in my coffee then I will just use artificial sweeteners. You really should try to not have any. Artificial sweeteners are bad for your overall health as well as Synapse XT, which is precisely why they should be avoided at all costs. Aspartame, also known as "NutraSweet", can damage the nervous system and cause problems with Synapse XT over time.
