Adenosine! Is this the answer to my sudden sleepiness?

Go ahead and ask... "Jason, what the heck is Adenosine?"
It's okay, I had no idea it existed 2 days ago, but I'm starting to wonder if IT is the cause for my 1:00pm to 7:00pm lathargy.
Yes, I've been experiencing this, as indicated by my last posting - overwhelming drowsiness around that time each day for the last 3-4 days. As you can imagine, it's been a bit concerning. This kick I've been on, seems to have been thwarted by some unknown agent.
Perhaps unknown...until now!
Yesterday, in my quest for answers to this new quandary, I explored many medical sites, stumbling on a NEW study done with Resveratrol and Adenosine. Apparently, in rats, it was discovered that resveratrol increased the availability or the production of Adenosine. This is exciting... which is ironic considering Adenosine makes you drowsy! (bad joke)
But I have yet to answer your question... what the heck is it?
Adenosine, as far as I now know, is a neurotransmitter, amongst other things, that promotes or encourages sleep! It is theorized to be associated with REM sleep as well. Now, I'm not sure if I filled you all in on my sleep lately, but my REM has been incredible. My dreams are like movies now - vivid and exciting.
But sleep is the name of the game for me since, at this stage in my personal experiment, that's all I want to do at that specific time of the day! Caffeine has been found to help, but it, now I understand, inhibits or blocks the action of Adenosine!
So, in other words, Resveratrol SEEMS to be increasing the amount of Adenosine in my brain. This causes me to get very sleepy at a specific time after taking my pills. The sleepiness slows my thinking ability, as it does with most humanoids (and rats, apparently!) and this causes me to "worry" that everything that I've gained in the last month and 1 week, is getting ready to be lost. So my anxiety elevates.
This is my new Hypothesis!
So, what am I going to do about it?
Well... I'm thinking that the Nitro 250 may be too powerful for me and my sensitive neuro receptors. I'm going to go back to the original pill I'd taken in the beginning, Pure's Resveratrol Extra. I'd love to keep taking the Nitro 250 (I think it's more consistent) but you can't cut the pill in half. So, I think I will start to just take one pill instead of the two of Pure and work my way up again.
I've gotta go but I'll keep you posted!
