Usage of until now

Solution 1:

Yes. "I had a normal life until now!" I would expect to hear as an ironic or slightly annoyed (possibly passive-aggressive)retort to a third party, just after a mildly unpleasant or strange event had occurred, that caused some inconvenience to your normal daily life, for instance, you had just stepped in to a puddle, that turned out to be 60cm deep...

Depending upon the circumstances, if a little more formal or as part of a serious conversation, it may be better to say: "Until now, my life had been normal."... This would imply that some thing had happened [The event], and your life had changed and become unusual, a little strange or unorthodox as a result.
