I was planning to say it to a very close friend of mine (Russian) who was sick, and I didn't manage to catch her in the morning.
Native speakers, how about something like "А всё тебе ладно/нормально было сегодня утром?" -- literally, "Was everything okay for you this morning?"

Or, if the context is not about sickness but you simply want to know whether the morning in general was enjoyable, what about a construction like "Надеюсь, что утро приятно проходило" ("I hope that the morning passed along pleasantly")??
