God bless you Craig. Strangely someone else posted a simliiar thread today, but more on how to study the Word of GOD without distraction. This is pretty much similiar.
Here is my suggested list of possible remedies:
1. Pray to GOD for guidance and seek wisdom
2. Read earlier in the day when you feel wide awake, refreshed, even when you wake up. Hint yourself with some caffeine if your body is not allergic or weak to it.
3. Put yourself in a quiet beautiful environment, like by the fireplace, backyard at night or local coffee shop/cafe (some are obviously not quiet enoug)
4. Read Christian books. There are so many awesome books at there. Some recommended authors are Joyce Meyers, Joel Osteen, Max Lucado, Billy Graham, John C Maxwell to name a few.
5. Try reading a different translation of the Bible, especially devotional bibles.
6. Like Yeshua said, pocket bible is a great idea.. Keep one in the car as well.
7. Theosebes suggestion as well, use concordence. That'll keep you busy and a new place in your studies / readings.
