I'm sorry you have been experiencing that. Anxious hypo/mania is so rough. Three hours is particularly rough. I've had more anxious hypo/manias than I can remember, many with anxiety or panic attacks, but maybe not a 3 hour attack. I hope the Buspar helps. If not, a prn can really help some people. I couldn't do without mine. I have 1 mg Ativan, like glennk. It does help. Sometimes I've taken 2 mg at a time. Another prn that helps me is low dose Seroquel. I have supplies of that prn mostly for developing mania, but it helps me with anxiety a bit, too.
