I 100% do.
When I'm on a big dose of opiates, I consider my current script a lot of Opiates, 4 30mg Roxy, and 3 10mg Methadone... a lot of opiates I NEED though for my 3 torn, and 3 dislocated discs in my lower back.. sometimes they touch my spine and cause extreme nerve pain.. It's happened to me 8 times.. and each time I ended up in the ER.. I've stayed up to 3 weeks within one visit...
They always gave me 40mg Morphine, 6mg Ativan, 25mg Promethazine, IV every 6 hours.
I wouldnt wish that type of pain to my worst enemy.
Anyways OT, While on a good dose of opiates.. My hearing is delightful.. music sounds amazing.. almost as good as XTC.
BUT, with no opiates and while in Withdrawal.. every bit of noise sounds like a train passing by like 3 feet close to me. VERY unplesant.
