Is that 11B as in the infantry 11b? You can do this. I wish I had great wisdom for you for today, but I struggled mightily each day and no little anecdote has helped (gum, seeds,water), except exchanging texts and PMs with folks on here.
I'm day 3 today, man. My day 2 was worse than my day 1. I already feel like today is going to be better than yesterday.
