I danced with that partner a few times but I was careful. I would get pain pills for my back, knee or shoulder (legit sources of pain, but I could deal with just OTC stuff) or tussinex for a drip cough (wasn't really that bad) and then I would use it up much quicker than specified. When I finished the last dose, I would be racking my brain about how to get more; if I knew my neighbor had some I might slip into his house and steal it. Just a few cycles of getting high on it and you want it that bad. I only took it when I was depressed; if I was hypomanic I would probably have sought it out illegally.
I don't have any specific advice. Just a little bit of understanding of how strong the pull is. if you aren't strong enough, you need to find people to help you resist.
