Welcome again norfolkgal
if rehab is out of the question, maybe you can swing by your Drs for their advice. I know you've detoxed before without apparent ill effect but its better to be safe than sorry.
I'm really sorry for all thats happened to you in the past but it's the present thats mnost important right now - you can beat this and you can start a new life without addiction.
There's tons of support here - you're not alone
