I had similar symptoms except I suffer from chronic nausea too. I had an endoscopy (camera down the throat) back in Jan and they discovered gastritis. I cant say the medication Im taking has helped a great deal but I hope that the periods of feeling well get longer with the bad days becoming more infrequent.
Hi Claire
I went to my health food store a couple of days ago and go a product call Candaid. It is to kill off Candid which is a yeast overgrowth in the gut. You can get it throughout the body too. Apparently a severe yeast over growth is like being a heavy drinker. The yeast ferments in the gut and is fed by the sugar etc. It also gives symptoms of being drunk blurred vision, uncoordinated, and hangover. I had all of those too. Headaches were very prevelent.
I have started taking the product and they also sold me Aloe Vera juice to calm my system down as it was inflamed.
So far so good. I am feeling much better now. I am also allergic to gluten and dairy which I had removed from my diet anyway.
I hope this may help you to heal your gastric problems. Medication won't help a candida overgrowth. I come from New Zealand so I don't know what you equivalent product is over there but it is a natural product not a drug. Good luck.
