Anyway, so I figured I go back to my house in Megaton and put the bottles in the NC machine before I accidentally drank one. As I was leaving I ran into that settler who is always a nuisance trying to give you something you don't need. I said to myself "Hope it's Nuka Cola". and it was!
So I have that extra bottle. I go back inside and get the other 29 bottles of Q. Go to Girdershade and (all the time wondering, which one should I give them to? I end up giving them to Ronald Lauren simply because his house is the first one I walk into.. It didn't turn out well, and, because I forgot to save, I have to get that final bottle all over again.
Drat. :facepalm:
