Breaking a water fast.

Today's day 11 of my water fast, and I want to start coming off of it tomorrow with a not from concentrate juice fast. I was thinking doing five days of that, then I'll have to introduce alcohol because I have to socialize with friends and stuff and they'll get pissed if I don't drink with them.

I'm probably only going to be having two shots of vodka each time we go out, so it's not like it should be too many calories.

All the while I still expect to be only drinking juice other than alcohol, so in total that will be 11 days of a water fast, and 11 days of a semi-juice fast.

How much weight will I probably gain during the juice part of it?

Oh, and I'm 5'7, and I think that I'm about 138 right now, at the beginning of this I was 148. If that helps at all.
