Yeah mine lasted for hours as well.. People usually have 10-20 minute panic attacks. It's difficult to explain to people, that it can last for hours...

My longest was 5 hours (In the hospital - In 2020).

I never had a panic attack where I didn't have a benzo - Otherwise idk what would have happened. I Googled this.. , and panic attacks are possible to last for 24 hours.

But yeah, you can take up to 3 a day at least, should help you worry less =] Cuz doctor said that it's okay.
