AIBU to have grounded my 21yo son

[asdx2]

Ds was brought home unconscious by a couple of his friends just after midnight having consumed in the region of 80 units of alcohol.
I have spent the whole night awake watching him to make sure he didn't vomit and choke or die from alcohol poisoning
Anyway once he was up I read the riot act, made him clean his room, strip the bed and make himself look presentable.I also told him he wouldn't be going out before next weekend bank holiday or not.
He is suitably chastened and shamefaced and hasn't questioned the grounding (I am by my own admission a strict parent).
Bit of background he is generally a delight, hard working with a responsible job in local govt. He has got drunk before but not to that extent and never to cause any disruption at home.
I didn't think I was being unreasonable because I have spent the night scared he was going to die but mentioned it to my friend earlier who said I was BVU as he is an adult and she couldn't imagine her 13yr old agreeing to be grounded
So thought I'd throw myself open to the wisdom of MN although can't imagine I'll let him off the grounding tbh.

Read the thread I acted out of fear, we talked it's resolved, he is currently cooking lunch for us all (his choice)No bad feeling here from either of us

Read the thread.

YwereBU to ground a 21 year old.

I would have found it amusing had my parents tried that!

To those who think 'my house my rules' If you were to move back to your parents due to marriage break up etc would you accept being grounded?!

He wasn't grounded,although he stayed in because he was feeling like death warmed up.
We laughed about my "grounding" him.
Considering I only ever grounded him once in all the time he was growing up (for putting his ICT teacher's car on ebay) I don't think he took me seriously anyway

'I would have found it amusing had my parents tried that!'

Maybe, but please come back and post how laid back you feel when it's your semi-conscious 21 year old brought back by friends he's vomited on.
Asdx2, you still get my vote for a sane and adult conclusion to the event.

AIBU to expect people to give you all info in OP???

Not old enough to have a 21 year old but have seen many friends in that state and was a nurse in a and e so probably seen worse.

Still amused at a 21 year old being grounded.

Op and son appear to be amused about it too now the danger has passed.

Im sorry but I think you are being unreasonable... I moved out when I was 16 and got in this state on many an occassion... (well not 80 units but enough to make me sick and pass out)

You can give advice and tell him how disappointed you are but you cant tell an adult what to do.

Ok, another apology for not reading thread.

sanielle when I first posted I had "grounded* him through shock and fear.
Once that fear had gone and he was conscious and up to a discussion we talked and sorted it out.
We both know we were ABU but as adults and friends even we aren't afraid to say when we were wrong.
Off now to eat the lunch he has cooked through choice because he felt he should make amends.
