How soon can I fast again?

I attempted a 12 day Water Fast and today I blew it after 5 1/2 days. I was planning on picking it back up tomorrow but have been advised not to by someone who has supervised many fasts. However, my blood pressure and pulse jumped almost immediately after eating. My BP, today, has been as high as 166/106 and my pulse got up to 123. Prior to the fast, my BP was running in the 180's/110's, but had been as high as 220/144. My pulse was consistently in the 90's or 100's. During the fast, my BP got as low as 132/80 and my pulse was down to 77... but only at rest. The moment I got up and did anything, it would jump.

Expert fasters, how long do you think I should wait before beginning again? Tweet
