I had a Stone C0ck a couple times the past two weeks and I couldnt' sleep

Ive been taking beet powder plain organic, I would mix a spoon in my cold apple juice and down it before jogging.

But lately ive noticed after 4 weeks of taking it, the last week my Penis stays hard longer, I woke up at 3 am yesterday with a boner and then tried to wait until it went down but it didnt go down for 15 minutes until I stood up and walked around. I then took a piss when it finally went flaccid and went back to sleep and wok up at 6:45 am.

This happened 5 times already in the past two weeks but I notice only when I take Beet Powder past 3 pm., If I drink it in the morning like around 8 with my breakfast I dont get the hard nighttime stone boners.
