23lbs in 6 weeks .. wow .. can we ask what diet you are using?
It's through a physician here in town; it's sort of like the HCG diet that you can research on the Internet. I actually give myself an injection every day--I hate needles, but I'm really desperate to lose the weight. Also get a B12 shot weekly. It also is only500 calories, plus MANY supplements/vitamins. I've never felt better in my life (I'm 59). Most of the time, it doesn't even feel like I'm on a diet! Mickey won't even recognize me!!
. These days I am no longer intersted in anything I used to enjoy/love... That includes Disney. 
Hope you are feeling better.
