"hi milemile i have been on doxepin many years for panic attacks before this medicine i stopped going out anywhere. you will be tired for a bit of time but it goes away . it stopped all panic attacks. never had one panic attack for 10 years on this medicine. but i stopped to try other meds for higher mood.  but when i stopped doxepin the panic attacks returned so 10 years without panic attack on doxepin is a good thing!"
