Yesterday afternoon I used 25 drops topically. I didn't notice anything obvious until about 4-5 hours later, when I started having some heart palpitations off and on for maybe 20 minutes. Just prior to this, I did start feeling an extreme sense of well-being, but I'm not sure how much of this to chalk up to the Cardenosine and how much to chalk up to the fact that I'd just had an amazingly good evening with my husband. It may have been a mix of both. Today, the few times I've needed to walk briskly (like to get in out of the rain), I've felt it in my heart/chest more than usual. Also, I woke up at 3:30 from a bad dream, and when I woke up for work, I was again having a stressful dream (I haven't been recalling dreams recently at all).
I'll probably wait a couple days and try a half dose first thing in the morning, to see if the response is the same.
Interesting, thanks. Please keep us posted.
