Hi Sissy
Welcome to SR.
I'm sorry - I have no experience with what you're asking about. I do agree with Anvil tho that it's clear your husband is doing something. That to me matters more than what specific drug it is.
I hope you're looking after yourself here. Being involved with a addict/drug user is often no picnic. I've seen it from the other side.
Please check out our family and friends forums as well. You'll a lot of experience strength
and hope there, and a lot of support and some good advice too.
