I think you might be setting yourself up for disappointing if you fast specifically for that. Some people don’t feel it. I prefer to do it for metabolic and longevity reasons more than anything. I can’t say I’ve had euphoria but I only fast for a few days
Varies from person to person. There are so many variables… How much toxins/chemicals are in the body before the fast started? How peaceful/chaotic is the environment where the fast is taking place? Just to name two variables…
I have never felt euphoric, but I have very high levels of energy while fasting. I don’t feel during afternoon, and I can focus much more and get more work done. I’m in PhD, and I can literally see the difference in myself. Now it could be because of other reasons, like not worrying what I’ve to cook once I get home, worrying about groceries and that I don’t have to do dishes.
