You wake up a few times during the night naturally, but usually you won't remember this.
I find that when my dream recall is high, I also remember waking up during the night more often, so yeah, this may be sort of a side effect.
Usually you're able to immediately fall back asleep after these though.

To be honest, I wouldn't worry about it, and I highly doubt that lucid dreaming can cause sleep problems.
Usually if I wake up from a lucid, I actually feel well rested and refreshed.
