Tongue Pullers work on the same principle as M.A.D.s except they pull the tongue forward directly by gripping it somehow, rather than indirectly by moving the lower jaw forward.

These devices costs around USD$150 to USD$250, depending on the no of devices purchased.

In order for it to work, the tip of your tongue has to be in a "suction bulb" at the front, and it is very hard to get the suction right. Either they wouldn't poke their tongue in hard enough and it would slip out during the night, or they'd poke it in too far and wake up with an aching tongue in the morning.

Of course, you'd get better at using it with practice, but the question is, do you want another day of sleepless night or quarrel with your wife, when we are talking about instant relief here.
