Anyone taking Remicade as well as Cymbalta

[Licorice]

Hey, I'm taking 300mg remicade every 6 weeks as well as Cymbalta at about 60mg/day. I recently weaned off of Cymbalta but found that my GI pain after eating a fairly large meal became quite intense for days (I'm waiting on CT results for the non-Cymbalta phase). I haven't experienced this kind of pain with eating since I started remicade, which started after Cymbalta and has been successful for 2 yrs now (holy-man, people live w/o pain while having crohn's?!). So I assumed it was the Remicade, and not the Cymbalta controlling my inflammation. Now I wonder if somehow, Cymbalta is muting my symptoms.
Anyone have any info on /experience with treatment using remicade (infliximab) concurrently with cymbalta (duloxetine Hcl)?
