Nice work man! Keep your eyes on the prize!
I'm using beef jerky as the oral substitute. It worked pretty well last time, especially the kind that comes in the can, it felt like I had a tin in my pocket still. The hooch snuff also worked really well last time too, so I ordered a few cans of that.
We had a quote when I went through basic training to help time go a little bit faster. "Live meal to meal and Sunday to Sunday." Helps keep your mind focus on something a little more enjoyable. Hope it helps
