I have a low blood sugar tolerance than I had before....eating stuff with a lot of sugar in it causes me to feel very sluggish and sleepy, like I am right now. It passes after a few hours, though. I have been eating less, and that's scary. When I went on Zoloft, I lost 25 pounds in 5 weeks. That's when I started to fear that I had cancer. Then I realized it was a severe adverse reaction to the drug doing this to me, and then I discovered how to taper off of Zoloft.
