There are studies about how glucose is the fuel that the brain uses for willpower. There are tablets of glucose for people with diabetes, for when their blood sugar is too low and needs to be corrected. Regular sugar is sucrose, which is broken down into glucose and fructose. It takes time for this to happen. In the studies on willpower, participants were given drinks sweetened with glucose. The tablets are more portable and they can help to boost your own willpower. It is probably a good idea to check with the pharmacist, though, to make sure that this would be a good plan. I don't really know. I actually went with hoodia tablets for a while. It is used for weight loss. My problem was that where I was working at the time, I wasn't allowed to bring in my own food and store it in my work area. There was a room with vending machines and there was only junk foods in them and soda. I was eating way too many of those little bags of chips, and drinking far too much soda. The hoodia helped me to avoid the cravings for junk food long enough to break the habit. It ended up saving me money, even with the cost of the hoodia.
