How much time do you think would be sufficient. I am pretty confident that i can do in around 2 weeks (past experience) but i don't want to risk getting this job on some fluke experience. Been running 2 miles a day, drinking a shit ton of water some with some fiber powder in it, and taking b complex pills already. I was thinking of testing myself next week to see where i am at. Not sure where i can get these kits.
