Hey guys,
I learned the issue of not being able to finish the special chemistry quest where kate takes the pill at night when sleeping.
And I learned it through staying up for 56 hours infuriated I couldn't do it, so I went and finished 100% all of the events with nick and julia in-progress quest.
So to get Julia to take the pill , u need to complete EVERY MIDNIGHT/LATE NIGHT EVENT ( IN PROGRESS QUEST WITH NICK AND JULIA), and that is when u go to sleep one of them comes and wakes u up in the night, now to complete every MIDNIGHT EVENT u may need to have a certain number of the other events with them completed like shower bathroom etc. it is a REALLY REALLY GRINDY part.
