Two major mistakes I made on that fast. 1) I was drinking too much water. During the early phases I was up to 5 to 7 liters per day, now I keep it around 3 to 3.5 liters unless I'm on my feet or sweating quite frequently. Too much water can be just as bad (or worse) than not enough. 2) Doing salt only (probably combined with the excess water intake) was demonstrably stupid. Now I supplement sodium/magnesium/potassium every day on an extended fast. I personally shoot for around 3k/2k/1k mg daily of each of those. Do not take them all at once, they'll go right through you. Remember 3k mg sodium is roughly 7k mg table salt. Avoid Magnesium Oxide, shoot for Chelated Magnesium or Magnesium Citrate, they have much better bio-availability. This may seem excessive for electrolytes, but I think it's a good starting point regardless of body size, and the solution to it being 'too much' is 'just drink water'. One Minor mistake -- I'd keep my diet much less full of junk leading in to the fast. That 60 days started over an argument with my significant other about about weather to cook two pizza's or one, and beer was involved, so... let's just say I didn't have the cleanest of slates going into the fast the next day. Other than that, I'd take better notes, journal more, and test my bloodwork more frequently -- both with my ketone meter and in a lab by professionals.
