Yay, acceptance of a problem is the first step to overcoming it.

I can imagine once you're hooked it can be a hard habit to break. Refined sugar is almost like a drug, the way you get that high when it spikes your blood sugar. To help strengthen your resolve, here are some good reasons to cut back:
1. Sugar weakens the enamel on your teeth making them more susceptible to decay.
2. Similar to #1, sugar also weakens your bones making you an easy target for things like osteoporosis.
3. The constant spikes in your blood sugar are very bad for your body, and will most likely lead to diabetes at some point in your life.
4. Refined sugar has a lot of calories, so the more you eat the more likely your body is to put on fat.
There are probably more reasons, but that's all I can think of for the moment. Fresh fruit is a great substitute for fruit juice and fruit snacks. I've also been told that taking chromium (a mineral supplement) can help cut the cravings for sweets. It will be hard at first, but if you can get yourself weaned off it your body will eventually stop craving it. Good luck!
