It's normal to worry about damaging your sleeve. I doubt you've done any damage by eating too fast.
I vomited when I ate too fast (it's happened to me twice since my sleeve 6 months ago). It's just your sleeves way of saying HANG ON IM NOT READY YET.
This is a learning curve journey - I'm still learning now.
I too worry I could stretch my sleeve or do damage, as even now solid or chewier foods are hard for me, they fill me with 5/6 bites. For example, in nandos I can only manage two wings and one slice of hallomi cheese. But my brain and auto pilot orders a 5 wing meal, 2 hallomi slices and garlic bread. Lol. Waste of food or what.
I'm still learning to order food and portion food to what my stomach can manage - around 50-100g of solid/chewy food and 150-200ml mushy food (chilli etc)
You'll be fine, the fact you're worrying shows you'll be great with your sleeve! xx
