I would have a conversation with your doctor about it. Mine went into a lengthy diatribe with me about how he thought it was ineffective, and how all the girls on the internet who claim they have seen benefit from it are wrong, etc. But, he also said he's willing to Rx it for mood swings. So, at my next appointment I told him I'd been having mood swings. Which, strictly speaking wasn't a lie, and he wrote out the script. Now, I haven't noticed any mood stability since being on it. If anything I'm probably slightly more emotional (I've also had some epic crazy in my life, so, who knows where that's to blame). But, I sure have noticed a LOT of nipple development. It happened fast too.
But, your doc does need to know what all is in your system to correctly evaluate you. So, tell him you want it, see if he'll Rx it, and if not, try and hint, without sounding all blackmailish, that you're going to do it anyway. A lot of time doctors will just do it at that point, knowing that it's safer for you to be doing it under their care than not.
