Same here.Prep's the worst.I know experiences differ so here's my input.Mix the prep and chill it for and hour or so.Although I didn't find the taste to bad,I used drinking straws to by-pass my taste buds.Get warm and comfy and try to make sure you have the bathroom free.Difficult sometimes if you have kids.Use baby wipes and nappy cream,or similar,as your rear end will get sore.I stared my prep at 5pm and couldn't get to bed until 2am.I still had to "go" quite a few times before my 8-30am apt.The test itself is OK.The staff go to great lengths to keep your dignity intact and make sure you know what's going on.I watched the procedure on the screen.It took about 30-40mins.If you're offered sedation,take it,as it will relax you,although not knock you out.But you will need a lift home.The doc should give you a rough idea how things are while doing the test.Then you will be sent an apt with the GI to discuss findings and what meds may be offered.That apt.could be 4-6 wks if it's with NHS.....There will be others around soon to offer their advice etc.Best wishes to you.
