I don't take my medicine regularly.
Why don't you take your medicine regularly?
It isn't natural and I don't like taking things that are not natural.
I know that you don't want to take anything that's no natural, but your doctor has prescribed these medications because you have a condition that requires them. You should discuss your treatment with your doctor before making any sort of treatment decisions on your own.
The doctor is a natural advisor to people
Not everything can be cured naturally. Depending on what you have the medications can prevent you from slipping further into disease.
