The only med on your list to worry about is the Ativan. I am assuming you are getting more on your own besides scripts if you are taking a lot.

Benzos are very addictive and build up tolerance fast. I know they work beautifully for anxiety because I take Klonopin. I have never taken more than prescribed. .5 mg twice a day.

If you can take only the right dose each day and never more and use no other drugs or alcohol, that is where you want to be. Trust me I know how hard that is. And the same dose ativan each day won't get you buzzed it will just keep the anxiety away.

With a history of opiates you know how dangerous the game is. You could switch to alcohol real easy probably.

I have been sober a long time but I know how much I want a little somethin somethin once in awhile like you. That is why I have ended up cheating with pot. I am not saying I recommend it. I admit I use it for an escape occasionally not a medical reason.
