It might be challenging to eat for a while. Avoid biting or licking your lips, and make sure no food or drink stays on the lips. Drink through a straw for the first few days. Do not eat citrus fruits and juices, greasy, salty, or spicy food until your lips are completely healed. While eating do not constantly wipe your lips with a napkin; do not keep licking your lips, as this will restrain the healing process
