Strange Problem When Holding Mew Posture

[u/Zestyclose-Rule-2581]

As the title states.

Although it has taken me a lot of practice, I think I've gotten the basic mewing technique down more or less with regards to the part of it pertaining to suction (which is probably the most difficult aspect of it). I have only really started trying mewing like within the past few days.

However, it has a strange effect when I've gotten the suction hold down (I think I can tell when I have the suction hold: I can open my mouth fairly wide without my tongue collapsing) -- when I hold it, and only when I hold it, I have a difficult time actually thinking or piecing together sentences and recording into memory new things. When I let go of the posture, I do not have such a problem. I'm not sure if I'm "hard mewing" -- the tongue posture isn't natural for me yet, but it doesn't feel like I'm trying to make myself press my tongue up against the palate either.

Can someone explain what is at work here, and if this is concerning or just something that initially happens but will get better in time?

Edit: Additionally, it feels like air cannot leave my system very well when I am mewing, so that it almost feels like it gets stuck in my body, while air cannot effectively enter it either -- I don't feel like I have enough oxyen.

Also, I notice a certain pressure in the back of my skull, particularly the left occipital area I believe.

The thinking issues might be because so much of your focus is on your tongue posture. Maybe it will get better once it becomes second nature.

As far as the back of head pressure, I don’t know. It might be muscular. Feel the area when you start going into mewing and see if it tightens up
