That fuzzy-headed feeling can be from an elevated blood sugar too!
Sounds to me that you are a sugar addict!
I used to be a severe chocoholic! Then, in 2001, I gave up chocolate for Lent. It was the most difficult thing I have ever done in my life! I wasn't sure I would survive it.......or that my marriage would make it through!

Seriously though, it did get ugly a few times. I felt like I was going through the same withdraw that cocaine & heroin addicts go through! I took it one day at a time. Making a trip to the store to get something wasn't so easy for me. The closest grocery store is 7 miles one way. We do have a "Mom & Pop" family owned store that is closer but they close very early and are closed on weekends. Whenever I would be tempted to make that long drive just for a chocolate bar, I'd rationalize just how much that it was going to cost me after adding in the cost of the gas to go get it..also adding in to the fact that I would have failed myself and God.
It was hard, but I made it! I expected to wake up the morning after Easter and eat the first chocolate I saw!

But, it didn't happen.....in fact it was 3 days before I finally ate some chocolate. And then it was my niece's birthday cake!
Now the only time I really crave chocolate is when I have PMS. I keep one of those small bags of Hershey Kisses (the ones with just 5 kisses in it) for that week.
Okay, getting to the point I was trying to make........IF you ARE a sugar addict, *please* try to find a way to control your addiction or more than likely, you will become a diabetic later on. And trust me, thats NOT fun!
