I'm thinking of counting my wife's acne medication as a non-necessity
Are you serious? Why would you consider her medication non-necessity?
Because it's time for us to get our lives in order.
If your wife requires a medication, even if it is for acne, then it is a necessity for her. Instead, you should get your lives in order by increasing your income. Getting another source of income will allow more flexibility in your spending.
What do you mean, we live comfortable.
I just think you should leave her medication on as necessary. I'm sure if you were in her shoes you'd want the same.
