Thank you for your query.
1. I would recommend that you avoid beer for one more week. I am assuming that you had a conventional tonsillectomy
2. The normal healing healing process still has large raw areas in the tonsil bed which may get irritated and bleed.
3. If you have a look at your own throat, you will still see a white slough in the tonsil area at the end of one week. This is a normal appearance of the tonsillar fossae due to the action of saliva on the healing raw areas.
