Honestly, I would wait and skip this years Halloween drinking binge

. its not worth taking any risks. If you later find your voice is not clean, or not high enough in pitch or if a suture opens at some point, you will always think that maybe its your fault because you had those drinks ...
Dr Kim says 3-4 months no alcohol, some drank occasionally some alcohol, but I don#t know if that included drinking a lot. I guess a lass of wine or beer or even a cocktail does not hurt, but having a bottle of wine or a couple of cocktails may be too much. Also I am not sure how Dr Habens sutures take the alcohol. Dr Kim uses permanent sutures, so they may be less affected by such things. For me, alcohol often also causes some reflux and that is clearly bad for the voice and bad for non-permanent surgical thread. Any acid is - which is probably why sour drinks and fruit juices are also not suggested.
