What helps me is to stay physically busy. I’ve gone 6 days. The hunger will hit you and then pass. Take a drink of water and stay occupied.Sometimes I’d go for a long walk with the dog.
But if you did around and think about when you’re going to eat next, you’re doomed.Think about work. Read a book (not a cookbook), watch movies, talk to old friends, drink herbal tea, sit in the sauna.That’s what I did.I hope this helps
