I believe we have similar body types. I have done two days fast on many occasions and although my head can be fuzzy at times, its manageable. In most cases I will drop 5-10 pounds with 1/2 coming back quickly. I am currently on a six-hour eating window and down to 204 pounds from 215 pounds.

I have thought about a five day fast and some friends have done them before and swear by them.

I was looking at trying one in July and then repeat the process 3 to 4 times a year if the process is successful. Like you, coffee is my drug of choice and its always difficult to go more than 48 hours without coffee. Friends tell me that there are health benefits to forgoing coffee, but it always sounds like a conspiracy theory to me.
