2 mos is very new in a big eating change and alot of healing and repair is happening inside the body.
plus your post doesn’t show your work/stress levels, what you eat, what ya do in a day, and so much more so your waking up, which is kinda normal in a way for so many millions on this planet I would say don’t worry about it. Do little things to work on your sleep and see how you do in another month or so.
I wouldn’t get worried up too fast on this one, very personal sometimes on how sleep goes off on big eating changes. They mostly correct themselves later down the line for alot of us.
if you are zc then increasing carbs how? with plant carbs? doing that isn’t the answer for sure but I know many feel they wanna experiement this way or that but if eating plant carbs, then your zc transition isn’t going the way it should ya know. all in zc, give it time
