My little sister doesn't have IBD or anything (touch wood) but when she needed some paracetamol for a cold she had (she hates oral suspensions) the way I got her past her fear was to get her to convince herself there was no pill.
I told her that when we swallowed food, there were usually still some solid chunks in there that didn't get mushed up properly as we chewed and she was in effect swallowing a pill whenever she ate. It's all in our mind, because we're trained to chew before we swallow, but I appealed to her rational side to accept that at such a small size it didn't matter at all.
Just put the pill on your tongue, and then imagine it's not there. There's no technique to it, no trick, no knack. Pill goes on tongue, and you drink the water exactly as you normally would.
Hole in one. (Geddit? :shifty-t: )
