Insane energy while starting Paleo

I've been eating strict Paleo for the last 10 days after quitting grains and sugar cold turkey, and over the past few days I've had boundless amounts of energy. Pre-Paleo I would sleep 8-9 hours/night and still feel exhausted upon waking, but these days I don't feel the need to fall asleep at my usual hour and nonetheless wake up well before my alarm. I also feel much hotter than usual - I used to have cold hands and feet and would always be freezing, and now I find myself continuously turning the temperature down and my circulation has vastly improved in my hands and feet.

My exercise routine has stayed constant throughout, so I don't think it is driving this. I feel incredible right now, but I don't want to get too used to this feeling in case I come off this "high" (or is it just my body finally working as it's supposed to after years of crap nutrition?) Any advice would be appreciated!

Enjoy it while it lasts, adrenals/thyroid will burn out in a few months and you'll start looking for answers, Ray Peat heads up

I went from SAD where I was so exhausted I would almost faint several times a day, to paleo where I have good steady energy levels, eating this way is awesome!

Don't worry, "scumbag brain" will adapt to your new energy levels and after a couple of weeks or months, it will all feel normal. Then you slip in your diet, go on a family reunion, think "oh some pasta won't hurt", go on a processed-crap-carbs-and-sugar binge and you'll feel like shit for a couple of days. Then you swear to never ever let your diet slip and given that you adapt again to your paleo energy levels, you'll slip again a couple of months later.

At least, that's my experience. Don't worry.

There's so many different contributers to energy (conversely so many things that cause fatigue). The big one that comes to my mind is gluten and/or all grains, since I assume you nearly eliminated grains on paleo. Gluten intolerance is very widespread. If you wanna test it, after about a month of being paleo you just reintroduce wheat into your diet and see how it effects you.

Edit: Oh, and another big one is sugar. Consuming tons of sugar in the form of fruit juice and cola drinks can cause major fatigue and mood swings.
