I have a sense that I am getting less than average deep (22) and REM (36) sleep, Total Z(5:50). Last night I took something called REMTyme, that has Mg, theonine, some herbs and melatonin and my numbers were deep (06) and REM (1:24) sleep, Total Z(6:41). It looks like it increased REM and possibly decreased deep. I have looked at the affect of lower dose melatonin in the past and seen no effect. These were among the highest REM numbers I have seen; I started using Zeo last Sept. Has anyone else found anything that they think increases either REM or deep sleep?
