Hi Maggie,
I am also going to go down the wig path. Have already bought mine in preparation for chemo and managed to get one that is pretty close to my normal hair, although I can say that mine is certainly not as exotic as ariel little mermaid meets cher drag queen! Talk about a fantastic description - love it!!! If you bought your wig then you can honestly say it is your hair - bwahaha!!!!
Keep up the great work on the treadmill and if you need to have some toasties cause they're the only thing you can taste then enjoy them knowing that your getting closer to getting super new taste buds that will be able to taste absolutely everything!!
As for the what if's - I'm thinking what if I win lotto!!!!! WOOHOOO!!!!!
Putting it on my list of things to do ;-)
All the best
Xx Cath
