Hello! I am currently taking Vyvanse and I have had some similar issues. I find that drinking ALOT of water was the key. I am 6’2 192 pounds and I honestly drink about 1 and a half gallons of water throughout the day at a minimum. You have to make sure to eat a balance diet throughout the day to avoid the potential for hyponatremia. I wish I had some other advice as you said you do drink a lot of water.
