Every person is different, so the mouthpiece can have some variation for each user. Some may find that the device suctions too strongly and makes their tongue sore at first, while others might feel the device does not have enough suction to keep their tongue in the proper position all night. If suction seems too high, most will find adding a bit more air to the bulb during placement of the tongue to be more comfortable. If suction seems too low, we suggest adding a small dab of olive oil in the bulb to create a better seal. With a bit of adjustments, and time for the body to become used to the mouthpiece, most users reach what we call the “Goldilocks Zone” where everything is just right, and the Good Morning Snore Solution is both effective and comfortable enough for use all night, every night.
