Will stopping Accutane while on holiday affect my results?

Hi, I have been on accutane for about 5 months or so now. I am going on holiday to vietnam for 23 days at the start of december. I am wondering whether I should continue accutane while on holiday at the risk of having to drink (not too heavily) while there, and in having lowered immune function at the same time, or if I should stop for 23 days then resume. If I stop will it affect my long-term results? and would I effectively be clearing out the accutane from my system and have to start over?
