Headaches are too often
It's good that you know you have sleep apnea. AM headaches are a very common symptom. Other symptoms are VERY loud snoring (like you mentioned), dry mouth, frequently have to go to the restroom at night, teeth grinding while sleeping, suddenly waking up feeling like you cant breathe.
Have you been to a physican about this? Untreated sleep apnea can cause serious health issues. If you havn't had a sleep study, or are using CPAP, I strongly urge you to look into it.
BTW, I have SEVERE sleep apena over 87 interuptions a hour (over 30 is considered severe). I am using CPAP, and very actively involved in my treatment (through gaining knowledge, questions, ongoing personal assessment). Ergo, I am NOT a physican, and I'm not giving you medical advice. This a friendly word, from someone who knows. I hope you will post to let us know how things are going.
All the Best,
Don
