I went to dr telling him I was feeling nausea and because it had been going on for weeks he said well its time I gave you something for your tummy. I have had an endoscopy and yes I have gerd but I have not had a follow up with gastro dr because well she only works 4 hrs a week and the follow-up from last May is scheduled for April I assume I have nothing too much wrong and my dr did get a written report which he says he has read. Anyway sorry for straying so my dr gives me a sample of tecta telling me to try it for a couple of weeks and let him know if it helps. I took the first one with my lunch on Monday and by dinner I was feverish and itchy and had symptoms like the worst flu I have ever had. I have not taken another but I am thinking maybe my body will get used to it?
