Avoid caffeine and any other stimulants. Antihistamines can help with sleep.
You may want to purchase a pill cutter if you don't have one. Although they are not completely necessary, they may come in handy when you get to the lower doses.
With whatever schedule you come up with, if you are dosing in the morning, I suggest saving 1/4 of that dose for the evening, and only taking it if you cannot sleep, and have already tried other supplements. It's pretty obvious though when you know that you will in fact need to dose a benzo in order to get any sleep, as benzo withdrawal has a lovely way of saying hello.
After a few days on a lower dose, I was usually able to at least alternate days of taking an even lower dose, and then returning to the other dose. It wasn't a set back because I had just been lowered down, so the lower dose was even lower than that of the initial lowered dose, if that makes any sense. I used to alternate, then stabilize at the even lower dose for a week or so, and then alternate taking an even lower dose, and repeat. The long half-life helps with this, plus if you have that 1/4 of the dose saved for the night time, then you can take it if needed, and like I said, it's not really a set-back if you are ahead of schedule.
