"i have been using amytriptyline for about 8 weeks now for chronic pain in my elbow following an injury. i started at just 10mg a night and after each 4 day period increased it by 10mg until i reached 30mg. this was on amitrip-10. as my body adjusted the pain would return. i was suffering from dry mouth, morning drowsiness until about 10.30am and certain level of confusion. i eventually had to increase to 40mg and was doing really well - pain free for the first time in 2 years. then the funding agency pharmac changed the supplier and my next prescription was amirol. i had to almost double the strength for effective relief, in spite of the claimed same dosage. so be careful if you change brands."
