Ease Me In (The more guarded approach):
I've been using [method 1] for a while now, and I understand the reasons we decided on it, but it's not really working for me. I saw an ad for [method 2] and was thinking that might be a better fit. What do you know about [method 2]?
Just Give It to Me (The no-nonsense tactic):
[Method 1] just isn't for me. I need something that [fits better into my life, doesn't have all the side effects, my partner can't feel, is less expensive, etc.]. What can you recommend?
