any recruitment ideas?

Welll...So far no one has answered my recruitment e-mail and I have sent out about two. I feel like I may change the format of the e-mail, maybe it seems very boring, not interesting to people...I'm not sure. Have you guys received it? Do you think it could be phrased in any way that would be better? Or a way that would draw people's attention more? I have a lot of people that have come up to me saying" Yea I saw your e-mail, but I'm not prescribed..." But as we all know I cannot use those people. I have on interview scheduled with one of my friends who is prescribed, and that should happen tomorrow. So I am excited about that. Besides that I am just reading up on the literature, trying to get as much stuff as I can. Although I will no be asking questions about illegal drug use, I do think that I will use articles that discuss it, just to put the medicine into some kind of context. Although I can't talk about it, I am not going to avoid a huge factor revolving around it..thats about it for now!
