Personally, I don't think it's a good idea to do such an intense fast so soon after doing a 10 day fast.
Fasting is great for cleansing your body, but doing these monstrous fasts back to back is probably going to have detrimental effects on your body.
IMO, you should probably only do a lengthy fast (i.e. anything over 3-5 days) at most once or twice a year. Once a year seems about right.
If you want to do habitual fasting, then a 2 or 3 day fast on a monthly basis is probably the most you want to do.
But more importantly, you shouldn't be doing ANY fasting until you consult a doctor and make sure you don't have any health issues first.
EDIT: Oh and gingko, if you're thinking about responding to this, please don't because I pretty much skim right past your posts at this point. Just thought I'd save you some time.
