Hi glenellen,
I just joined the forum yesterday, I'd say all the support and answers you need are in here somewhere. Looks like you did a great job on the weight loss already. I hope you sort out the hair loss issues. I was reading another post earlier and someone said to take an unflattering picture of yourself and everytime you are about to waiver in your resolve, take it out and have a look and remind yourself that you no longer want to be that size and if your true to the diet it will work.
You have allready proven to yourself that you can do it. A stone in 3 weeks is fantastic.
My sisters hair falls out all the time (she'd kill me if she knew I was saying so). She does have a full head of hair so if yours is coming out in clumps best consult a Doc.
Looks like the IRISH section of the forum is a bit quite huh.
Anyway best wishes in your quest to be healthy. Give me a shout anytime you want to talk.
