Can it be done to lose weight around 50 pounds by November to see twilight with a girl-friend of mine?

by november 2011? yes. i lost 40 pounds over summer break. im in college summer break is like 4 months or something. so you got like almost a year to lose only 10 pounds more than me. also at first your gonna lose weight fast as hell, then it will slow down. just add in some extra miles to your running when the weight loss starts slowing down. try new exercises too. gl you can do it.
