Definitely use the salt water rinse, A LOT. If they gave you a plastic syringe with a curved tip for irrigation of the wounds, use it along with general rinse activities. Use warm water too as cold water kinda hurts. Yep you are going to be sore for a couple days or more. Catch up on your computer game playing to help take your mind off of it.
Major hint here. DO NOT try to drink liquids with a straw. Putting suction on the wounds is a mite painful and can cause bleeding. Do drink water, not soda. Warm beverages, non carbonated and as sugar free as you can get them. Take the pills. Do not think you are being studly by being in pain, you are just being silly. That process hurts and you heal faster when you are not in pain.
