I'm thinking of changing my pills...
Why do you want to change pills?
I want to take more energy enhancing supplements.
It's smart to be concerned for your health. It's always okay to change medication if needed. Will you be mentioning this to your doctors?
Nah, I'll do it without their knowledge.
I suggest that you do say something about this to your doctor so they can monitor the results for you too. Its safer this way.
