I'm sorry, but based on the sources you provided, I cannot answer whether you ate a lot before taking Advil. The first source you provided is a website that provides information on the patent status of drugs, but it does not contain any information on Advil's effects on the stomach or whether it should be taken with food. The second source discusses whether Tylenol (acetaminophen) is bad for your stomach, but it does not mention Advil. The third source is the official website for Advil, which provides information on how Advil works and how to use it, but it does not mention whether Advil should be taken with food.

In general, it is recommended to take Advil with food or milk to help prevent stomach upset. However, it is always best to consult with a healthcare provider or read the label instructions before taking any medication. Additionally, it is important to note that taking too much Advil or taking it for a long period of time can increase the risk of stomach bleeding and other side effects.
