This is how it went for me. But before i do, let me tell you that i can drink up to 10 cups of coffee, and fall asleep fine.
I'm up to 3 pills a day, i can fall asleep fine, i feel good, BUT, this is because im on my 3rd day of 0 carb diet. If i wasn't on these pills, i'd probably feel really shitty right about now, lethargic, retarded, tired, sick, etc...
But taking these, i forget that i haven't eaten any carbs for 3 days, and the glucose-ketone switch is beyond unnoticable.
I've stated on another thread in the diet section, that once in ketosis, i actually feel livelier, and i have more energy/endurance/strength on 0 carbs. So, probably by tomorrow, i'll feel even more energy.
I guess the pills right now are just ameliorating the switch to ketosis, and stabalizing me.
I've slept fine so far. I'll come back with more results like in 2 or 3 days and tell you how i feel after the switch.
