The exhausted all the time, achey all the time and sinuses sound alot like me and I have Fibro. I hope you don't but just something to think about talking to the doc about. When I become extremely tired the Fibro flares up and even if I have not changed anything in my daily habits or diet except lack of sleep the IBS comes roaring into the foreground. The lack of sleep triggers the Fibro and IBS is a symptom that comes w/ Fibro (all though not all IBSers have Fibro) and so the Fibro sets off the IBS. Or you could just be plain all tired and your body is just complaining right now.
I hope you feel better, Christie
