im gassy and in pain... this sucks

 Jon, I agree that you might want to cut the probiotic and start more slowly (or try a different brand, if it is the PDU giving you an issue).

That said, though, it is possible to suddenly develop lactose intolerance late in the game. If it's not the probiotic, you might want to try eliminating that just to see.

Just riding in on the coat-tails of others who have said it's probably the probiotic- I started the ultra primal preop and thank god i did, the gas was horrible, it took about a week before it calmed and i could take it everyday and i got up to 2 a day right before surgery. It took about 2 months altogether. But I'm glad i took it before, because with surgery and that added gas would have tore me up- good luck!

So far today I didnt take it and I habe no pain. I didnt really eat any real food yet though. I will see how I am later, if no issues today I Ill take a PDU tomorrow and see if it is beneficial to be to go every other day.
Btw I think the probiotic was also stopping me up...cant have that either.
If cutting the probiotic doesnt help Ill try the elimination diet suggested by airbender

Thank you all for the advice and the detailed responses.... dunno where Id be without youo guys
