It doesn't always help me either, Anna. I take the time release kind because my problem is not getting to sleep but rather staying asleep long enough to be rested. The thing is, it's hard to compare. Subjective. If I take it and don't have a great night's sleep, maybe it would have been worse without the pill? Who knows? But it is an antioxidant, my cardiologist says it good for me.
Benadryl works best to make me sleep. If I'm desperate, I take that.
