I remember that some time ago I find in one of the Tim Ferriss books, that the reason for feeling tired when you wake-up is due to low blood sugar. Also he recommends to consume a snack with 150-250 calories before going to bed. My question is not about what do you think about it, because it will break the forum rules.
Tim recommends to have snack of flax seed oil in combination with the celery and almond butter.
The question is about what to take in order to replace those products, because I can't find them to buy.
