5 HTP can act as a stimulant in some, so I would personally stay away from that one. No idea about the others.

Is there any remote chance she could have undiagnosed bipolar disorder? Sleep issues with us are rampant.

If not, she should see a sleep doc. What about sleep apnea? What is the shape of her jawline as seen from the side or profile view? Is her chin prominent? Small and not prominent?

What has she done about basic sleep hygiene? Room quiet? Dark? Good temp? Is she physically safe where she is? Noone stalking her, no dangerous exes or relatives? Does she have a trauma history? An anxiety disorder perhaps?

I cannot exercise within several hours of any sleep attemptt. I end up all amped up for awhile.

What is her caffeine intake like? Any Yerba Mate going on? Other stimulants?
