Stuffing

How quickly can my stomach expand if I still drink one liter after eating on a full stomach? How much more can I do one week later?

"It depends"

If you're already quite stuffing yourself during normal eating, then I would assume not much will happen. If that's your initial starting point, then maybe you can drink a liter more than you can do now?

There's only one way: let's try and find out.
Keep it fun and keep it safe - get used to the "full" felling and go a bit further every time. Don't expect the capacity growth too quickly, or you might get sick and loose the fun in it.
I love to reach that point where I can't suck in the belly any more - how far do you go while it's still enjoyable?

I think I'm already filling myself up a lot. The question is how quickly will my stomach expand if I drink another liter every day after eating?

If that liter gets you to the "my belly feels stretched, I can't fit more" feeling, then it will definitively expand your stomach and increase your capacity.

If you ate little and that additional liter afterwards does not make you stuffed, then I doubt it will change your capacity over time.

ich denke, wenn du das jeden tag machst das man schon in 1 - 2 monaten mehr hineinpasst. wichtig ist dern magen wenn er voll ist gut zu massieren, dadurch wird die verdauung angeregt und es passt schneller wieder was rein.
