Thankfully I'm used to it by now. I too suffer from insomnia but his snoring doesn't bother me at all. Now it's awkward when he's not there! I do need some ambient noise like a fan going (no music, that makes things worse). If I have that then his snoring tends to fade into the background unless it gets to the horrendous trying to breath through his nose and mouth at the same time noise. Then I just nudge and he turns over.
I will say it did take some getting used to, esp. when we weren't spending every night together. Now that we live together it's not much of an issue at all.
