Hi Gina, sorry you and the Porcelain God have been hanging out a little too much. I have been through that also. My sugar is fine but my body is objecting in a big way to 20 minutes on the treadmill. I tried a couple of thingd; I think what i found was eating to close prior to working out or drinking to much fluid while working out. Small sips work even though you sometimes feel like you could drain a small lake to deal with your thrist. Once you start working out your body reduces the blood going to your digestive system and so if there is too much in there you get that sick feeling and then the invite to visit the Porcelin God arrives soon after.
It is Awesome you are in the gym, just experiment a little with food, fluids and I hope it helps.
Take care
Phil
