opiate withdrawal
"Have become an Oxycontin addict, snorting daily to the tune of about 50-100mg every day for about 2 years. Without methadone my physical withdrawals start with sweats/fever first, then the muscle spasms/restlessness, aching everything and inability to sleep joining, then the nausea/loss of appetite following close by.  There is no peak once you've started the game, it's always maximum bad until the end. One symptom is relieved due to time, and another quickly replaces it. 5mg of Methadone every 8 hours nullifies all physical withdrawal problems for me except: hot flashes/inability to regulate body temperature, and total loss of appetite.
