Breathe Right Nasal Strips work brilliant for snoring, but below is some more information I found at http://www.webmd.com/sleep-disorders/tc/…
Losing weight. Many people who snore are overweight. Weight loss can assist reduce the narrowing of the airway and possibly reduce or eliminate snoring.
Limiting the use of alcohol and medications. Drinking excessive amounts of alcohol or taking certain medications, particularly sleeping pills or tranquilizers, before sleep may worsen snoring.
Going to bed at the same time each night and getting plenty of sleep. Snoring may be more frequent when you have not had sufficient sleep.
Sleeping on your side. Sleeping on your side may eliminate snoring. Attempt sewing a pocket in the middle of the back of your pajama summit, putting a tennis ball into the pocket, and stitching it closed. This will assist keep you from sleeping on your back.
Promptly treating breathing problems. Breathing problems caused by colds or allergies can disturb airflow, main to snoring.
Using nasal strips. Nasal strips, such as Breathe Right, widen the nostrils and improve airflow.
I could not find any information on drooling while sleeping.
Hope this helps.

Yes – I drooled and snored terribly in my sleep. I went to the doctor and was referred to a sleep specialist who told me I had sleep apnea. This happens commonly to overweight people. As they drop off to sleep the throat relaxes and closes off the airway causing momentary suffocation, and waking up to a degree. This cycle can go on all night and result in feeling tired next day (because you dont get deep sleep). It is fixed by using a CPAP machine – wich is a machine that blows air into a mask you wear at night that exerts sufficient air pressure to keep the airway open. Its not uncomfortable, and works well.

Those nose strips (breathe right?) really work for snoring.
I don’t reckon the drooling can be stopped unless you sleep strickly on your back.
