Hi! Brand new here. It was suggested I try keto by a nurse about 2 weeks ago, so I thought WTH, and did it. 3 days in, had a carb night, but since then I have been staying around 30 - 40 a day. I exercise ALOT, and am not doing this for weight loss. But I cannot believe how much better my brain 
feels! And I am sleeping so much better too. Way less anxious thoughts during the day.
Has this happened to other people?
Welcome. Yes, some of us transitioned without so much as a hiccup. Others had a more difficult time at first, but eventually got there. I think it depends a lot on what and how severe the prior damage caused by eating SAD for years or decades. Or genes maybe.
There’s no money in healthy people and/or carbs are addicting. Especially in sedentary people.
Yes! That happened to me back in 2018 and no turning back! Best change I’ve ever made in my life. Except I am closer to 10 carbs a day now.
In the absence of dietary glucose (also known as carbohydrate), the liver makes ketones to feed the brain. Ketones also have a number of profound hormonal and epigenetic effects on the body. So your sense of well-being is founded in the biological effects of a well-formulated ketogenic diet.
YES and another yes along with tons of other benefits 
ya stopped polluting your body with what they market ‘as food’ out there. off the chemical slurry sludge of processed food.
clean eating, clean life, clean brain
so happy for you doing so well!
Yes! I’ve been on clean keto for over three years and everything feels better - and I lost weight!
Good for you!
Yes, this is normal.
It didn’t happen to me but I was already on low-carb since years and my brain already felt okay on high-carb (very nutritious but waaaaaaaaaay too much carbs to my individual body), never expected or wished it to get better and it never did.
On other areas, yes, going low-carb felt a bit better (it couldn’t feel much better as I felt very well and healthy on high-carb and I still don’t have much energy, I probably never will. it’s not so bad and probably changing other factors - even harder than changing my woe - could help eventually).
But 30-40g was just like 80g to me except I got fat adaptation and that was cool
Going way later later (especially with plant carbs) gave me another boost, still the same brain and not much better energy levels but it helped mentally and I always feel a bit better physically if I lower my carbs.
But some people feels worse if they go even lower. So do whatever floats your boat And listen to your body, it may want something different later. My woe definitely evolved and I couldn’t have done it in one go…
