When I take my meds with Dr pepper it only takes about 30 minutes for them to start working vs water at about 1 hour or more. The meds also last longer when i drink Dr Pepper. They last for about 3 hours ( a total of 3.5 hours vs 3 hours total with water) which means i get an extra hour of up time (0.5 hours because they start quicker and last 0.5 hours longer When they crash at the 3.5 hour mark it is at least 50 % less than when i drink water. I know this sounds strange but fore me it just works. I drink about 1.5 to 2 liters of Dr Pepper a day.
I thought at first that it was only n my head but i stopped drinking Cola for about a month and i had more down time.
Try it it just might just work for you.
