A member asked:

How many days does it take to change an eating habbit?

A doctor has provided 1 answer

21 days!: You could change your eating habit starting today. It has been said that it takes about 21 days to form a new habit. By continuing to eat in a new way day after day, it is going to be hard not to eat in the same way after about 3 weeks. But it's up to you to start that process today.

Very good morning doctors. If I take multiple medications at the same time, does the order in which I ingest the medications matter? If the order gets changed on other days does it matter, or should I take the medications in the same order each day?
