I did the barium swallow and I'm not going to lie...it was gross lol. It's not the taste, because it is tasteless...it's the THICKNESS!! I had to swallow 3 different ones. The 1st part taste like sprite, wasn't bad. The 2nd one was rough...had to swallow it in 3 phases. The 3rd one was more rough because I was lying on my side and had to take big drinks and swallow it...not gonna lie...I almost lost it lol. So if this is what you are doing it is tolerable but it is rough. Best of luck to you and you got this!!
