Honestly, I was thinking awe, so nice to see nonya, chmuse, keangkong commenting on a thread and then I realize you've resurrected a thread from over a year ago....
But to answer your question. I personally don't think vacation is anytime to stop treatment. I personally think that's when I'll be most weak and wouldn't want to mess up my progress. With a small milligram vial, I would personally just let it come to temperature and chuck it. Maybe even take a few extra milligrams on Friday 😂 and then chuck.
