The Ativan is a class D med, is the only thing I would add to it. It caused my first miscarriage. So when you're on it, please be a safety girl

The ativan worked great for me though, but like the others said, just take it when you need it - it kicks in fast, so try not to fear another attack, and relax when you feel one coming on. I've progressed to where I don't need the Ativan anymore, so maybe one day you won't either. But for the time being, it takes about 15 minutes to kick in, at least mine did, so only as needed.
