I have Barretts and had 3 gastroscopies in the past- the first was fine as the sedation knocked me out. The second was unpleasant and I noted that I had 5g of midazolam. For the last one I received 2.5g and I thought I was fighting for my life - choking, retching, panicking. Now it's time for my next endoscopy and the consultant says he will only give me 2g as this is now the maximum. Is this correct? Could I find another consultant? I'm inclined to say no - I'll take my chance with the Barretts!
