well it can take 1yr or more off ur life. try 1 soda a day. Pepsi is better 4 u than Diet Pepsi bc Diet can take yrs off ur life

theres no sugar in diet sodas. but there is soo much sodium. you are actually dehydrating yourself because the sodium is absorbing the water and retaining it. i would just drink regular water if i were you. some diet soda is ok but you shouldnt drink it like water.

try alzheimers! the artificial sweeteners in diet pepsi and diet coke cause either that or liver failure in the long run

In general, soda is not good for you. The acid is hard on your teeth, and the aspartame in diet isn't super good, either.

Not to sound critical/harsh, but 5 2-litres is excessive. If I might make the suggestion of buying a twelve-pack or the smaller 8-oz cans, and limiting yourself to one a day, perhaps you could wean yourself off?

Or, add Kool-aid + Splenda to carbonated water or something similar?

diet Pepsi really isn't that much healthier than regular Pepsi. You do have a chance at cancer, but then again MANY thing can "cause" cancer. I would suggest cutting down on it and adding some water in your meals. you need water for a lot of things you do. there is no nutritional value in diet pepsi & I've heard it contains unwanted chemicals. Instead of real sugar, (which is contained in regular pepsi and if you have to much it is stored in your body as extra fat) diet uses aritificial. so i'd say cut back a little, but you can still enjoy it once or twice a week!
