I enjoy the 'quiet' of 3am like some people enjoy the 6-7am morning, and not that I haven't experienced that as well, but from the 'wrong' end
You described me, too.
Caffeine or nicotine, for me both eventually reach "the law of diminishing returns". I enjoy them more at start of my day.....as day wears on I just find them less enjoyable in larger amounts.
Nicotine is good for a lot of things. What it isn't good for is Raynaud's syndrome, stuff like that in extremities. Talked to several people here who moved to no nic and noticed their extremity circulation problems resolved markedly.
For most other things nicotine is very beneficial.
While i"m here: I wanted to mention this a few places anyway, as sort of a public service announcement.
Does anyone know if there are any animal by-products in VG? I should probably look this up quickly. Because, unfortunately, I got diagnosed at major univ. hospital recently with a (previously rare but increasingly diagnosed) "alpha gal" antibody. To make a long story short, my blood showed exposure to the Galactose-alpha-1,3-galactose (alpha gal for short) which causes a pretty bad (and often deadly) reaction to mammalian meats. A forest ranger died last year at Cossatot from anaphalactic shock many hours after eating red meat because he had a high reading of alpha gal (mine is very low) but it is being found in a lot of outdoorsy people who have had tick bite(s) (hunters, hikers, loggers, fishermen, etc.) and chigger bites. Apparently, the tick saliva has this carbohydrate in it, and so do mammals, so there is something that sensitizes people if they have had a tick bite or too many tick bites. The reason it has been under diagnosed is that all food allergies until now have been from binding to food
proteins...in this allergy, the antibody binds to a
carbohydrate present on meat called galactose-alpha-1,3-galactose (alpha-gal.) The other reason is that the reaction is extremely DELAYED. 6-8 hours later. So people are waking up in middle of night with hives, digestive problems, swollen faces, and in some cases, full blown analphalactic shock. And for probably 20 years, nobody could pin down what the allergic reaction was from in many cases (meaning many people have been denied useful treatment because nobody knew).
The good news is that my digestive problems will probably improve markedly, but the bad news is that if VG has mammal anything in it, vaping is "curtains" for me. Can't take any chances now. Will be living on chicken, fish, and veggies from now on though. Duck. No lamb, pork, beef, venison, etc. I think I can eat squirrels. I had to throw out all my vitamins that are inside "gelatin" capsules (from red meat animals) and switch to the ones with vegetable cellulose. (want to lessen my "load").
I always get the *weird* things that science hasn't figured out yet, but this one is going to be seen more and more I think. Univ. of VA and a few others are doing a lot of studies on it......f'-in bugs. It's both ticks and/or chiggers. I lived in CT before this, in "tick central" so it could have been CT or AR where I got this antibody.
So this is also an alpha gal alert. Dress properly in the woods, while mowing lawns, etc. and use Deet or spray clothing with pyremthrims (sp?).
By the way, don't freak out. Not EVERYONE who gets chigger and tick bites is gonna have this problem. I guess a number of things have to occur, it is dependent on a LOT of different things.....and you have to have just the right immuno biology for it to happen. Some of us are just .......lucky.

It is not even a test that anyone outside an immunology specialty would agree to test you .... I've been thru over a year of working with immunologist to find out why I feel so crappy yet everything keeps coming back showing how amazingly "healthy" I am. LOL
I'm not a huge red meat fan, so I will not be suffering as much as some of the people I've talked to.....it would just about kill them not to be able to have a juicy burger or grilled steak or pork loin. This will just make being invited to dinner more challenging for me now.
