Does Benadryl (=diphenhydramine) lead to tolerance? Can I use it to help with sleep?

Question

I am an insomniac and all the sleep medications that I've been prescribed have eventually had no effect on me -- I built a tolerance to them. It's a dangerous thing because I don't want to take lots and lots of all sorts of sleeping pills to get to sleep -- that's unsafe. I heard that Benadryl might be a good alternative. It currently has an impact on me, but will I eventually build a tolerance to it? Thanks!
