There are still needless calories in Gatorade. Less than your typical non-diet soda, but far more than water. It can be a rough switch at first so some of those extremely low calorie water flavor items (be them powder or liquid) can be a good alternative to plain water.
Way back in high school the army recruiter spotted me working in the computer lab and tried to talk me into joining up. He told me the toughest it ever got for the computer techs was working shifts and sleeping on a cot in a hallway, and even that was rare. THEN he found out I had asthma and told me I wouldn't make it through basic, and even if they re-instated the draft I wouldn't be going anywhere. I'm fairly certain I wouldn't have joined, anyhow. Just not the type of life I was looking for.
I insist we only use organic insulin for all of the newly diabetic cows! It's sustainable... or something.
