Yes, you can be addicted to colas. The caffeine is addictive. Some people can also get hooked on the processed sugar and corn syrup used in making sodas, because that also produces a stimulating high. So sodas provide a double whammy.
The diet sodas are not an improvement, as the sugar substitutes used can have toxic side effects when over consumed, or in people who are especially sensitive.
The fizz in sodas is also bad. It causes calcium to leach out of your bones and teeth and get flushed from the body. In essense it dissolves them.
I suggest switching to healthier drinks with no caffeine, however, you will go through withdrawal symptoms from both the caffeine and the sugar for a while afterwards, so I suggest using a long weekend or vacation time to stop drinking soda.
Some of the alternatives are:
- Water--if you tire of plain, you can add some fruit juice, but pick one with no added sweetener.
- Juice with no added sweeteners
- Skim, lowfat, or 2% milk
- Soy, almond, rice, or oat milks. They come in plain, vanilla, chocolate, and some I believe have strawberry.
- Herbal teas--I really like peppermint tea.
- Postum--it is a caffeine free grain substitute for coffeine, but you should not drink it if you are sensitive or allergic to wheat and related grains.
There may be others I missed, but this is most of the alternate choices out there.
