My hubby just stopped drinking diet soda after almost 18 years of being addicted to it. His withdrawal symptoms are going away and he is feeling much healthier. It is also easier for him to eat less too
If I drink soda I prefer diet. That's usually because I find it not as overpoweringly sweet as regular sodas are. Regular soda seems to also give me a headache if I drink too much of it where as if its diet I don't get one. I try to stay away from soda though and stick to water, tea or juice, but I do like to drink some every and now and then though.
