The next year, Lo released "Habits", which received positive feedback from music blogs and led her to sign a record deal with Universal Music Group.  Lo's first EP, "Truth Serum", was released under the label on 3 March 2014, and entered the top 20 in Norway and Sweden.  Three singles were released from the EP, including a remixed version of "Habits" by production duo Hippie Sabotage, re-titled as "Stay High".  The track peaked at number 13 in Sweden and reached the top ten of the charts in Australia, New Zealand, and the United Kingdom.
