Shev143; My guess would be that even those who say drink on Purim would not say to get stone drunk to the point of vomiting and certainly not to drive while intoxicated.
In the case of getting drunk that is what is clearly wrong, and I do not know of any Rav who would say otherwise.
As for shidduchim you are right.
I just wanted to make it clear that when it comes to Halacha, what is mutar or assur, there certainly is a right and wrong and when it ‘looks’ grey, it siomply need to be looked at more closely or looked at by a Rav who can sift out the black from the white tell an individual “You should do (whatever he says) in this case”.
