For me, Stagg brand Chilli (be careful of the dynamite flavour - don't attempt without sour cream or a glass of milk!!) works well, think it's a combo of the spice and beans.
It's yummy too (well I think so). Just be aware of some gassy repercussions...you know, spice and beans..
And kiwifruit work a treat as well.

After talking about food, I hope this isn't too gross, but sometimes a shower or bath helps...perhaps the warmth, erm, softens the business end of things a bit?
Ewww.

Anyway, hope you find some relief.
