I think as long as you take your vitamins, eat right and get enough sleep most nights of the week, you'll be ok. Just don't make the staying out late a nightly thing, which I'm sure you don't.... I used to just panic all the time when my husband was in college. He went to architecture school and they would pull all-nighters all the time. I was so afraid that he would get run down. So I know what you mean. Get a good night sleep tonight!
In memory of the sweetest german shepherd I ever had the pleasure of knowing. I love you, Duncan. 3/12/02 - 12/19/11
