Yes, sugar can make your brain act strangely. Stevia does not act like sugar in our bodies, but does continue our cravings for sugary foods (see: What About Stevia?.

From what you have told me in your comment, it sounds like you are depressed. When your body is failing you or you are in pain, depression is a common reaction. One of the signs of depression is an inability to focus and plan activities. It is good you are getting out and exercising (this can really help depression), but strange that it is causing you to feel down; if the pain is worse after exercising you may be dealing with Chronic Fatigue Syndrome and not Lupus.

I would suggest that you work with someone local for both your Lupus and general health. Here is the link to find a Naturopath in your area: American Association of Naturopathic Physicians

One more thing…I love my choclate & goodies & such. I crave them. That is how I found your website. Could my thinking problems be connected to my sugar intake? I try to stick with Stevia. Does it act like sugar in our bodies? Thank you!

Thanks for the comment! Peanut butter is actually a great thing to eat because it really stops sugar cravings. I think it is because of the high protein and fat content of most peanut butters and even the natural ones taste sweetish.

I would say that you should probably move to the natural peanut butters. Smart Balance is okay, but still contains molasses. If regular peanut butter is all you can get, it is fairly low on the glycemic index – so, probably not too bad.

Good luck on your sugar-free adventure! If you haven’t already, download the 30 Sugar Free Days PDF; it should help.

What do you think about the sugar content in peanut butter? I am on my 5th day sugar free but still eating JIF, which I know has refined sugar. I am OK with having 3 grams of refined sugar a day. BUT do you think this is going to make me crave more sugar? Should I switch to natural? What about Smart Balance?
