Oh Pat...it hurts to even read about your knees! I'm babying mine along until I cannot stand it any longer and then will have a replacement which is why I am trying to diet....trying being the operative word! After a nice loss in March I managed to fall flat on my face...not a good month, April. Have been using meal replacements and my inner self is telling me they're not healthy...so, I'm waffling on a program and like those here (I"m sure) I've done every program twice. Take care of your knees.
I'm in for the May weight loss challenge.
