#1- stay away from opiates (including Ultram/Tramadol, a synethic opiate agonist/antagonist ... Withdrawal from that is similar to withdrawal from Nubian & Methadone. Worse than typical straight opiate agonists like heroin or morphine, etc...).
#2- stay away from NSAIDs such as ibuprofen(Advil/Mortin), Aleve, asprin, etc... NSAIDs are COX2 inhibitors that block prostaglandins. If you inhibit prostaglandins, you eliminate the signal to start recovery.
#3- if you're gonna use a "pain reliever", use Tylenol/acetaminophen/paracetamol, since it's not an NSAID, but blocks pain signals in your brain.
* tylenol may be rough on your liver, but your liver can be repaired. Advil can cause irreparable kidney damage (imagine your kidneys going from nice cushy filtering sponges, then imagine those kidneys turning from spongento coral :/ ).
#4- ice.
