Based on the information provided, there is no specific time frame given for how long you should wait to drink milk after taking Advil, which is a brand name for ibuprofen. However, the NHS website ([2]) mentions that taking ibuprofen with food or milk can help if you have a sensitive stomach. This suggests that it is generally safe to drink milk at the same time as taking Advil or very soon after.

However, it's always a good idea to consult with a healthcare professional if you have specific concerns about interactions between medications and food. They can provide the most accurate and personalized advice based on your health history and current medications.

Remember, this information is based on the provided sources ([1][2][3]) and may not cover all possible scenarios or individual health situations.
