20 day fast, 7-9 day break, on day 6 of 15 fast

I went for a 20 day fast with 7 days off and now Im on day 6 of a 15 day fast. I have an ultrasound on the 18th and will fast into it... curious if the tumor will shrink or not... during my week off I began to eat TONS of potatoes ad sushi after day 3 of refeeding. I did not load up on mineral rich food because that starch is what I craved! my Hubby who was 6'6 and about 210 is joining me for support... its his first and he is doing it with ease... freaking out a bit about the weight loss, but I assure him he will gain it all back! I am quite skinny but will keep going to day 15.
