Note:
Signs that your regulator needs replacing:
Depending on the location of the regulator rectifier, the part can easily overheat. Other causes for a dead regulator rectifier center on the battery. Ground connections are important for good voltage, and if there is a faulty voltage, the regulator rectifier can run hot. Bad grounding, corroded battery connection and poor or loose battery connections will cause faulty voltage too.

There are generally two ways for the regulator rectifier to fail:
The first deals with diode burnout, resulting in battery drain. It is easy to assume that the issue is a bad battery because of symptoms such as dimming headlights and poor starts. Checking the voltage with a voltmeter versus relying on symptoms alone will prove highly beneficial. If the voltage drops below 13 volts, the motorcycle will begin to drain the battery and eventually the engine will stop. Check for bad connections and corrosion; these can also cause voltage issues.
The other failure type is shunt regulator burnout, where the regulator rectifier fails to control the voltage, resulting in battery overcharge. Again, a voltmeter will be useful for diagnosis. Though generally, readings above 17 volts mean the regulator rectifier is not converting the excess power correctly and all of that excess voltage may cause the headlights to become extremely bright and then blow.

Good to use every night...I do.
If you suffer from dry mouth during the night, these are the perfect solution. I had tried rinses - they don't last. Sprays - they don't last. lozenges - don't last. Other tablets, only last a few hours. I can get about 8 hours relief with these. Contrary to other reviews, you do not suck on them like a lozenge...they won't last at all if you do it that way. Read the directions. They "adhere" to your back molars...don't drink or eat after putting them in...as both will either dislodge or reduce the effectiveness. However, when I don't use these, my mouth is miserable and so dry. These provide enough moisture throughout the night. The flavors aren't too bad. I've used the mint (not may favorite because I'm not a fan of mint flavor), orange and berry. I wish they had other flavors (cinnamon, licorice), but till then, I'll use these probably forever.

Really helpful for dry mouth.
Scent Name: Berry, Size: 100 Count
These really work. I wear a CPAP and my mouth was so dry I was waking up with my tongue stuck to the roof of my mouth. They stick well so no worry of swallowing it during the night. I like the berry flavor.
