OK... let's talk about your foot care.
It is CRITICAL that you take good care of your feet while you are getting your diet and blood sugar levels under control.
Here is a tip I developed that you might find useful.
Keep your feet free from injury which includes proper removal and control of dried skin. I found that a proper stool or "chair" in the bathtub when I take a shower is very helpfull combined with a seperate little tub for my feet to soak in.
I use an old Coleman ice chest to sit on because it is very sturdy and there are several sizes so it is easy to find one the right height. I put the ice chest on it's end. They are sort of non-slip because of the texture of the surface. The little tub for my feet I picked up at the Dollar store. This way I can take my shower and add a little dish detergent and anti bacterial hand soap to the "foot water" and get a good soak which removes the dry skin and thoroughly cleans my feet. Since I have been using this shower/feet soaking method my feet are much happier and the places that dry skin was acumulating have gone away completely.
I have considered removing the handles off the ends of the Coleman ice chest that sits on the bathtub floor but the thing folds up flat enough to not be too much of an angle to sit on. If there is a stability issue for you it wouldn't be that hard to knock off the end handles with a screw driver and a hammer. REMOVE any sharp edges before ya sit on it ya goof! Or your feet won't be your only problem!
