DUDE! HELL YEAH!
That's awesome man! Congrats! KEEP IT UP! You should feel proud!
Tapering is soo important, especially with sub. It's more powerful than people think. Getting down to those specks (I've been there....it seems like it's so small that it's not going to do anything) is tough with eyeballing them and the dose being so small, but it is crucial!
Seems like a lot of people start getting low and then try to jump off at something like 0.5mg and still struggle for a week.
I finally kicked late October 2010, so it's only been a few months, but things are soo much better and manageable in my life. I feel so much happier! :D

I don't have crazy up and downs every day anymore either.
The next part is really important. Don't feel obligated to jump into anything too serious, but it's really crucial to start having fun and/or healthy activities to do. I'd say that exercise is an absolute must, as is eating/drinking well.
Keep us updated and keep going man! You made it this far, you're almost there! Be patient and you'll soon have days where you don't NEED any opiate and you'll feel fine!
