Thank you Fallout, I’ll keep an eye out for any negative effects. On the second day of Gingko 500mg (with the first dose at 9pm, then again at 9am the next day). I did wake with a fairly stiff erection, which is unusual, but it immediately subsided after getting up. My testicles do feel a little looser, but nothing significant, and during the day, when resting a laptop on my lap, I did feel an erection forming. That isn’t common, but there may be no association whatsoever.
On the mood side, I felt slightly more talkative than normal, but that may have been a coincidence. It’s only day 2, and I’m not going to run to conclusions, especially after a couple of times where positive effects in the past have ceased over a three day period.
