I did the flush this morning - this time by the book:
- Took 1 level tsp of pure ascorbic acid (3g vit.C) with 1/3 tsp. baking soda to buffer the acidity, in a glass of water, every 15 minutes. That's the recommended dose for a "moderately healthy" person - i.e. not "healthy" and not "sick" - which is where I judged myself to be since I'm recovering from mono.
- I started getting diarrhea after 4 doses (12g), but the "flush" effect only hit me at 10 doses or 30g vit. C. Let me tell you, it is unmistakable. I definitely didn't reach this point in my last experiment with vit. C tablets.
Conclusions? Well, I decided to do the flush today because I'm still feeling a bit off from last week when I taught the kids' Capoeira camp. I had to be up 4-5 hours before my normal waking time, slept less, compensated with caffeine (which I haven't touched in over 6 weeks), and did a couple extra Capoeira classes plus hill sprints with my very fit friend (that's what Ido's girls do when we want to bond

). "Feeling off" for me is being slightly depressed, low or no motivation to train, pretty much lack of motivation for anything. I woke up pretty blah today but after a few doses started feeling energetic, wide-eyed and alert, similar to the feeling of fasting.
I'll report later as to how long this effect lasts.
Also, for anyone interested in giving this a try, definitely use a buffered form of vit. C or add a buffering agent, or you will burn your rectum.
