I've just been put on this med - I hate having to take anything, but these anxiety attacks are getting way too hard to handle on my own.

I know I've seen a few ladies here mention that they take/took it. I was hoping I could get some pointers as to what works best in terms of taking it (timing, food/no food, etc.).
I've already covered all the basics with my doctor, but she told me to take it whenever I wanted to and I'm trying to see if there's a better time to take it.
Any advice?
