Continuing to drink a Beverage after Birchas HaMazon?
What should I do if I want to Bentch - for any number of reasons - but I want to continue drinking?
Should I:
- wait to Bentch until I've finished drinking;
- Bentch and make a new Berachah before and after drinking; or
- Bentch and make a Berachah after drinking?
What are the principles to consider?
Sources, please.
