I'll try the pepermint tea - but from past experience I never enjoyed it much.
Well, I eliminated the Alpen Light bars from my food intake today - and I am wind free - so it was obviously having 2 of those as my HEXB that was doing it. Such a shame as they are really handy and really tasty.
Maybe I will just have one in future, and have something different as the remainder of my HEXB, but certainly not liking the wholemeal bread!
