My wife and I had similar symptoms earlier this year. She tried a proprietary medicine and kept to her usual diet. I read on the internet to try the hot water method but starve the body for two days. Three days later I had no symptoms but my wife was still struggling but getting better.
We are all different, but I read that starving the body helps prevent the bacteria, which are causing your symptoms, from multiplying and the water flushes it out.
But I'm no doctor!!
If the symptoms persist seek medical advice.
