Go to the drug forum, I suggest basic drug discussion for starters, have a look around and see if the drug or drug combo has come up in a thread title and have a read around to see if someone has brought up the question before. If so you can add your question to it or add anything you like to contribute from your experience.
It's no hassle if it's been talked about already as asking is the best way of finding out your answer. Just dont ask for drugs as that is not going to go down well :D
