Hmm, I had the same general problem when I got my tonsils out. Huge pills and I was never fond of pills in the first place there were only 2 ways to get them down without gagging I found and they were:
-cut it in half and take it in halfs (not sure if its a capsule or a pill if its a capsule it wont work since the stuff will fall out)
-get a pill crusher and shatter it then put it in a high flavor drink (gatorade works good because the acid in sodas may fuck with the pill) It tastes pretty bad but if you have huge problems taking the pill this may work
Also Im curious, how big is the pill and are you drinking lots of water with it? I take pretty big pills with little to no problem as long as I take alot of water with it (I can do it without water but ill gag also)
Not sure if this will help but worth a shot
