I have been working as a customer service representative in an office setting for about a year now. I've had IBS symptoms for years but it wasn't until November 2009 that my symptoms got so bad that I started going to the doctor. He diagnosed me with IBS-C and told me to take Metamucil daily as part of my treatment plan.For a little while I was doing great but lately whenever I work the late shift on Thursday nights, I am plagued with severe abdominal pain. It's so bad I've been sent home early and I can't even stand up. The only position I'm comfortable being in is laying down. The pain has actually had me in tears once.. With my job, it's very low stress which is why I like it but I have to sit down for long periods of time. I like to wear the most comfortable clothing as possible to limit the pressure it puts on my gut. I usually wear comfy old jeans that are a size too large, or leggings with a skirt. We have a dress code so I'm not allowed to wear athletic type pants or sweats. The pain started getting really bad a few weeks ago.. And I actually cut back on my hours because of it. However, this also means less money.For some reason, the pain gets really bad during long night shifts. When I work the long day shift I get uncomfortable bloating usually, but not the severe abdominal pain that I get at nighttime. I've tried everything! I've even gone so far as to not eat anything except for a banana or something easily digestible on my break. I tried getting up frequently, stretching.. nothing works.Does anyone have any advice for me?
