I was very ill after having my fourth baby, so ended up in hospital on a cocktail of 3 IV anti biotics and went home two weeks later on oral antibiotics, within a few weeks I had severe stomach pain, crawling skin feeling on my back, upset stomach, rosacea, lethargy, athletes foot and psoriasis, foggy head etc and the list could go on! I realised what was going on after knowing someone years back who had suffered from a yeast infection, the doctors wouldn't hear of it, telling meto eat sugar and yeast as normal due to feeding a baby, I discovered threelac and then tried fivelac and they coupled with a strict no sugar diet for a year made me well, I can now tolerate small amounts of sugar in foods, but I take fivelac most days to keep myself well. The difference is amazing. I feel unwell when I don't take it.
