My problem with melatonin has always been that it goes through my system too fast, and my eyes pop open after 4 hours. Even some time-release products give me this problem. The Natrol TR acts more gently and lasts longer - anywhere from six to eight hours.

I use boswellia when I feel a headache coming on, and it has stopped them every time over the last 2 years. (I don't know if it would work as well once the headache was in full control.) My doctor told me that boswellia is an anti-inflammatory. I often take a ginger root capsule at the same time as the boswellia, because it's my understanding that ginger has a similar effect.
