I was having cravings and was at 70 mgs, and I started having the physical withdraw symptoms about 8 hours after my dose and then later in the night having drug dreams, cravings etc. My counselor asked me why my dose needed to go up and what I was doing or happened to increase my metabolism of the methadone. Well I have gained 20 pounds and also started an exercise regimen, it is also Summer in Florida and I have been sweating my ass off in this heat. My counselor said that being in the heat does not increase methadone metabolism that it is a MYTH and that gaining 20 pounds would not be a good reason for increasing my dose either. She also said that she didn't think that my exercise regimen was strenuous enough to warrant an increase. Well why, pray tell, am I having the withdrawal symptoms, nausea, muscle cramps, cravings, sweating, chills/fever, and yawning, tears etc. The nurse that doses me agreed that I needed to increase my dose 10 mgs to 80mg (i usually do 5 mg at first but she said since my dose wasn't lasting at least 12 hrs I should go ahead with 10mg). Why would my counselor and nurse have such divergent opinions on my dose being stable or needing to be increased???
