Hi K.,
I disagree with one of the previous posters, you DO NOT have to get used to it, yes it is important for your family to bond, but it is not right that you should be suffering through this.
I was the exact same way when I was pregnant, I became such a light sleeper, and of course I stayed that way after the baby was born. Like being exhausted from getting up at night with the baby wasn't enough, no I was soooo exhausted because I was awake when DH was snoring! Like the previous posters suggested, check out a sleep clinic, sleep apnea seems fairly common nowadays, DH got diagnosed with it about 2 years ago.
He feels totally different when he wakes up in the morning, and of course keeps on snoring when he forgets to wear his mask. And after so long, I still haven't gotten used to the snoring!
I wish you good luck, if you would like more info or I can even give you the name of our doctor, just contact me.
