Due for an endoscopy due to upper left discomfort, acid and loose stools.

I went for one a few weeks back but unfortunately, due to my high anxiety, I couldn't do it. Also I have terrible gag reflex, I can't even swallow a tablet without gagging

....I tried my best. I had the throat spray (which also made me gag when it touched mu tongue) and sedation. The sedation had no effect at all so I just couldn't do it. 

I had a call saying that it needs to be done again as my stomach discomfort has been going on for about 6 months but I'm so nervous about it going wrong again. I know I need it as my stomach is getting worse.

Any tips on how I can get through this?
