Unsafe tap water

After having suffered with bloating and stomach discomfort and experimenting with my diet, but not having a full resolution, I decided to see if drinking bottled water instead of tap water would ease my symptoms.  I did notice an improvement when not drinking tap water.  I have more than once returned to tap water to test whether it really does affect me, and each time the symptoms have returned.   When my daughter went travelling and was given a water to go bottle, I decided to try it out for myself re our local tap water in order to save buying so much bottled water.  I am happy to say that the water to go bottle has been as effective as bottle water in reducing my symptoms, I therefore use it happily on a daily basis and am very grateful to enjoy the purer taste, and a more comfortable stomach as a result!
