caffeine and Vyvanse; pissing it away???

[drminaq]

Hello BLers
I have a question i hope someone can give me a straight answer on. Does caffeine's diuretic properties cause you to pee the amphetamine out of your body?
I once took Dexedrine xr 45 mg a day and it was perfect (once pulverized and plugged of course). My doc switched me to Vyvanse and i thought the fun was over. To my surprise I love Vyvanse, the only problem is my dose {(60 mg Vyvanse) = to 25ish mg} of Dex is way too low and the price of Vyvanse is prohibitively expensive.
I am looking for ways of increasing the potency of my meds and caffeine pills seem to work but I am peeing like an 85 year old man with prostate problem.

Does anyone have any suggestions to help me get through the day without that 4 clock crash. I take magnesium, try to eat well, sleep lots.
Thanks for your time and good luck!

Caffeine increases the effects of dextroamphetamine from my experience.

yes but does it acidify the urine or make you metabolize it faster?

i would guess that the diuresis caused by caffeine would increase the excretion of any molecule in the urine, other that certain ones that have a physiological role.

however, the potentiation from the caffeine would probably outweigh the increase in excretion.

but, i think the caffeine would mostly increase adrenaline, and that would make for a more jittery, anxious, and sweaty experience.

thanks all. That is interesting that caff. stimulates your appetite, that would be nice. Though i personally dont like adderall without opiates or benzos or a rubber hammer. I still hesitate to mix the two I have been using kratom with relative success on cognitive function, I dont get the opiate feeling from Kratom at all I have taken up 25 grams and it always makes me speedy. This might be the result of a past opiate addiction. But like 5 years ago, does tolerance ever go away?
