What mones can make you sleepy?

I know there's something that is making me really drowsy, but I always wear a mix of different blends so I'm not sure what's causing it. Last night I wore Vibe and Bliss with Love Potion's Sexology. After about 2.5 hours I got really sleepy and ended up taking a nap for 3 hours.

I don't think it's the Sexology since I wore just this on Wednesday and didn't feel drowsy at all.

Here are the contents of Bliss:

AndrosteRONE-Sulfate, Alpha-AndrosteNOL, AndrostENONE, ALLOtetrahydroxycorticosterone (ALLO-THDOC), DeHydroEpiandrostArone (DHEA), Dipropilyne Glycol, Alcohol Denat (SD40B).

And here is Vibe:

Alpha-AndrosteNOL, Beta-AndrosteNOL, AndrosteRONE Sulfate, ALLOtetrahydroxycorticosterone (Allo-THDOC), Dipropylene Glycol, Alcohol Denat (SD40B).

I looked at Akelah's spreadsheet and see the THDOC can cause sedation. Can this be what's making me so sleepy?

Thanks!
