There are 2 tricky parts to it: 1. The first 4 weeks. Always tough when abstaining from a habit. 2. Remembering that I'm doing it. After a few months, My biggest enemy will be staying on the ball, as it won't be such a foremost issue in my mind once the novelty wears off. Other than that, I should easily knock this flat (even 100 days is easily long enough to get a GF if I felt like cheating. I still expect well over 2000 comments on this bad boy).
