Thanks for the advice. However, I use an elliptical machine everyday in the morning instead of a walk. It is difficult to walk outside on really cold days or really hot days. I exercise everyday on my elliptical in the morning, and some small weights at night, but I found walking in the evening kept me awake before trying to go to bed to rest and get some sleep. Also, 3-1/2 years ago my doctor told me I had pre-diabetes. I didn’t want to take medicine and my doctor agreed, because I could handle it with going to a nutritionist and change what I eat and exercise everyday on my elliptical and it has worked. I go to the doctor every 3 months for an A1C check and you are not supposed to get over 7 on your A1C and I have kept my A1C continuously at 4.8 which is great. I also keep a journal of every meal I eat and not the calories are really more important than keeping track of the grams. I hate taking medicine if you can fix your life with a different lifestyle which includes less and better food along with exercise. I probably gave you information you probably didn’t need. I just want every one to know that medicine is not always the answer. I just have to figure a way not to take an insomnia medicine. I have spent a lot of time trying to refine my life without meds. For me, it is taking one problem at a time and finding a doctor who would rather not give meds, but to treat you with wholesome food.
