What can I do to deal with my loud snoring? It creates sore throats when I wake up and is embarrassing

Depends how severe. You should consult with your md as snoring may be a sign of sleep apnea. Dental devices can be very effective to control both non-apneic snoring and sleep apnea. Losing weight, avoiding alcohol or sedating medications, and getting a good nights sleep regularly all can help as well.
Get seen. It can do worse, ruin your marriage and cause you not to get enough sleep at night. If the simple measure of sewing a tennis ball into the back of your pajama top fails, see your physician about a CPAP machine or throat surgery. Sometime's is simply huge tonsils. Good luck.
