Well personally I feel if you can't be comfortable with talking to your doctor about a new medication that you have the wrong doctor to begin with. But aside from any feelings of awkwardness, it could also save you $150 and another appointment. It can't hurt to ask, I made it quite clear to my last doctor that I was going to use marijuana despite his ignorant beliefs, it's not like he can call the cops on me so why should I worry?

But hey, I haven't heard of Herbology...that's in PS? I'd definitely be interested in this other place if you could point me in the right direction
