That was my thought too. If it is this awful coming off of it, what the heck is it doing to the inside of a person's body? Messing it up!
I'm also coming off of caffeine and carbs. Whoa. tough.
I'm not sure you'd find a pulse on me without caffeine. Keep a journal if you can to note all the changes you're going through and how you feel after you've purged it out of your system. I don't know if I'd try it, but if it goes well with you, I might consider it - sugar anyway, not caffeine.
I'm up to two 60 second planks a day. I'm not attempting the challenge anymore. 270 seconds all at once seems impossible. But two 60s are good. Better than most people can do.
Also, I've thrown in the towel on my New Year's resolution to floss everyday. I'm no good at it - I get the floss too tight around my fingers and it's hard to reach my very back teeth. This has been my New Year's resolution for about 5 years in a row. Clearly, I'm into failure.
