Sleep Apnea Treatment

My husband wakes me up just about every night b/c when I snore I all of a sudden stop breathing. Majority of the time I wake up with headaches and sometimes I am fatigue. I clearly have sleep apnea & was just wondering if anyone knows which works best of the chin strap or mouthpiece to stop the snoring & help with the sleep apnea. I wanted to try this first before visiting the doctor. ~Thank you
