just a thought: you wrote that you take the probiotic in the evening and you have wind afterwards during the night. And since your probiotic contains FOS it might be this that is causing the wind. The wind is a byproduct of bacteria feeding, ANY bacteria; so if you are feeding the good bacteria with what they need (FOS) then there may be increased wind. I certainly get this from having FOS. I take my FOS separately and have noticed that if I don’t take that much in one go then there is less of a problem.
