Mamahawk, you are doing so great, despite how you feel. Despite feeling like crap, here you are trying to help someone else. That's really cool.
Good on ya for doing this hard thing. You probably already know that the maximum daily dose of tylenol was recently advised by the FDA to be reduced to 3 grams a day to avoid liver toxicity. At 16,000 mg, that 16 grams or more than five times the recommended dose. I hope that you find the chance to get tested for liver damage, and avoid all other liver toxic substances -- alcohol being at the top of that list.
Snowflake, as you see on SR, many voices chime in to try and inspire your resolve to quit opiates. And we are only the ones who actually post. There are LOTS of people who read these posts and get something out of them, who never actually post. Hopefully, getting inspired to quit their drug, too. There are a lot of people out here wanting you to succeed at becoming a non-opiate user once and for all.
