    I recently went on a boat ride with my cousins and had no complaints of snoring. The Somno med appliance is very successful and worth every penny.

    At first I found the appliance was bulky and appeared to 'fill my mouth.' I used it part-time for the first few nights. Snoring ceased immediately.
