I'm on day 17 and I'm not really fatigued, but i am starting to sleep more soundly and getting real restful sleep. The first week I had the fog bad, basically hallucinating for quite some time. Drinking lots of water helps, and so does excercise, you might think it would make you more tired, but doing some light cardio or some pushups etc in the middle of the day will get your blood pumping and wake you up, yea, you'll be tired later, but probably at a more appropriate time, and you'll sleep better. remember to keep drinking water, your body needs it a lot right now. gatorade wouldnt hurt either, to replace the sodium that you were getting from dip. Keep pushing, I quit with you brother. Dig in for the long haul and make the promise every day. you will be beyond happy in what you're doing.
