If you have too little, there can be issues with hard starts and especially lack of power, where too much pressure can severely damage your costly injectors. This simple to install gauge
Especially as we modify our Cummins with rail pressure boxes, such as the TS MP-8, put on larger CP3's, or dual CP3's, it becomes vital to monitor rail pressure to ensure we are not creating excessive pressure, but also to ensure we're not simply creating enough. If you have too little, there can be issues with hard starts and especially lack of power, where too much pressure can severely damage your costly injectors. This simple to install gauge plugs in-line with the factory rail pressure sensor, so there's no need to splice into the factory harness.EV² electronic gauges also include an integral programmable warning light, which may be activated if you select the checkbox above to add the programmer tool. The programmer can also be used to adjust the backlighting curve to perfectly match the factory dash lights, and can also adjust the amount of signal filtering/smoothing that the software performs.
*NOTE: Images may not show the exact gauge, but they do show the correct R38000-Style, which is an excellent match for 2010-2013 Ram Laramie Longhorn factory gauges.

Time release is the best way
I like these time released tablets. Time release is surprisingly hard to find unlike the immediate release style tablets. Time release allows for a longer sleep pattern as it enters the blood stream slowly over time allowing it to stay in you system. Immediate release will hit you hard and fast but your body will metabolize within a couple of hrs leaving you without the melatonin in you system. I took off a star for being pricey, but these do work very well.

Source Naturals Melatonin is the best!
My husband and I have been using Source Naturals Melatonin for almost 25 years. I have tried a few other brands, and I definitely think Source Naturals is the best! I once saw a program on Discovery channel about how Melatonin is an important heart antioxidant, and that after age 40 the Melatonin in our system goes way down. We had also just moved to a high altitude town, and I was having great difficulty sleeping because of the high altitude. We started taking Source Naturals Melatonin, and I was able to sleep like a baby. I really recommend the time release especially, and we also take a 1 mg sublingual lozenge to fall asleep more quickly.
