Sounds like you are through the most of it.
I would watch out for the temazepam. Benzo withdrawal makes opiate withdrawal feel like a party. I would have rather died than make it through it.
Opiates does not have a PAWS by the way. That is only with the Benzo's. It sucks.
I would definetely hit a meeting. Call a local NA hotline and find a local meeting or talk to someone if they have that capability.
The getting clean is the easier part, the staying clean is the trick.
God luck,
