Thanks, all for the encouragement.

greenlantern - my son is the one who inspired me. He is 5' 8" and was 287, He has lost 126 lbs and is now 161. His doctor has taken him off all medication and breathing machine! He is able to do anything he wants without being worn out now. I figure @ 5' 4" I have another 71 lbs to go before I make my goal.
