One of my coworkers has diabetes, and for him it is a daily struggle.  When he was first diagnosed, he had a hard time maintaining sugar levels, and it took some getting used to for him.  It first he just thought he would be alright if he watched his diet and exercised regularly, but he soon found out there was a lot more to it than that.  He had to eat at specific times, and not just be cautious of what he consumed.  He also had to get into the habit of carrying candies around with him at all times, just in case his sugar levels dropped.  There were other subtle changes in his life that also helped him.  Instead of taking the elevator up to our fourth floor office he began taking the stairs, and he also started walking more places and riding his bicycle.  To tell you the truth, I think those are things that everybody should do.  The general population would be much more healthy if they made simple changes such as walking the stairs in favor of the elevator and walking and riding bicycles from place to place.  Perhaps if more people made these changes, the number of people diagnosed with diabetes would drop.
