Been dope sick. It is pretty horrible. I alternated by being very hot and sweating so much I soaked the sheets, to racking chills that were only made bearable by lying in the bathtub and letting the hot water pound my cramping abdomen. Oh, lots of dry heaving too. I don't recommend it.
I highly recommend "The Zen of Recovery" by Mel Ash and I read "365 Tao" as my morning meditation.
Hang in there, it will get better,
Ted
