Emetaphobia & Prep

I’m scheduled for my Colonoscopy and Endoscopy on Sunday 28th at 8am. My doctors attempted this months ago but I couldn’t tolerate the endoscopy so we had to reschedule.

I’m in the UK and have been given Plenvu but I have severe Emetaphobia, ARFID, Autism and severe nausea, bloating, rectal bleeding and pain (hence the procedures). I struggle drinking even a litre per day.

I am absolutely terrified of this prep. I had an enema last time as I was just having a flexible sigmoidoscopy but now have to do the prep instead. My diet is so limited anyway that all I am able to stomach is plain sandwiches and plain pasta which is already a really low-fibre diet and I don’t think I’ll cope with the flavoured liquids.

My nausea is horrific and I’m scared the prep will also cause nausea or will make me sick. I already take Cyclizine for nausea but still suffer significantly with it.

Please let me know any tips, tricks and advice on anything! I’m obviously going to do my best and try and take the prep but I’m so nervous!

Thanks so much!
