Never tried it.
When I have a funky sleep schedule I use benadryl. The capsules hit faster and don't last as long. If I just need to fall asleep 1 capsule... if I need to fall asleep and stay asleep (longer periods or weird hours) I mix capsules and solid pills. 2 capsules and 2 solids work great for camping or day sleeping. I`m a SUPER light sleeper so anything wakes me up, and for camping we normally go to bed earlier than I do when at home so I have to make myself sleep. I took it almost nightly for 1 whole year a few years back then stopped, and now only take it camping or when I have to sleep odd hours. Works good, and is super cheap.
