How safe can it be to ingest a neurotransmitter? Aspartame is part of a brain chemical. Who wants to mess with your brain chemicals?

Actually, after saying that I must admit that I will allow myself up to 1 diet soda/ day at work only. Sometimes just water won't do it.

When I want a fizzy drink at home I mix a small amount of juice in a glass of club soda. It's not that many calories and seems to do the trick.
