I've been using the hacker's diet exercise program for about 18 weeks now. I exercise for less than 15 minutes (more like 10, at the moment) every morning immediately after waking. I've noticed that when I get up and exercise first thing, I usually don't need to drink a soft drink to get up any more! Apparently exercise wakes me up and replaces my need for a caffeine jump-start. I've been wanting to reduce my caffeine intake for awhile, so this is a welcome discovery.
I've also switched to diet drinks most of the time. This seems to be helping the weight go down slowly, too. Unfortunately, I hate most diet drinks. I also find the store brands, which I usually purchased for sugared drinks, make really crummy diet versions. I've found diet Dr. Pepper to be one of the best so far.
