Gerrie - When I take Benedryl for sleep, I usually take 25mg.It will not work for me 3 nights in a row. Two nights is fine, but the third night it will actually reverse and keep me wired up. I m not saying that will happen to Brig. Just be aware of tne possibility.. It offers me great benefit 3-4 times a week. Another great advantage to Benedryl, if it works is that it is very cheap, over the counter and the generic is just as good, even cheaper. It is also available in liquid. Good luck. Terrie
