Glad your finding this place helpful. Im afraid im not on lebvid so i couldn't comment, but i think panic attacks are fairly common among IBS types. Its the fear of being caught somewhere without a bathroom and just the worry about having an attack while out!What type of IBS do you have? Do you have D? There are lots that can help with D that i can help with, but im not so cure on C.If you have any questions fire away!Spliffy.
