You might want to make sure they're not interfering with each other, the Duac and Differin; I'd suggest letting them out of your sytem first after a couple of weeks, trying one on its own, stopping for a few weeks, then trying the other. Mind you, I'm not a doctor, but I used Duac and one other facial acne treatment and they messed with each other horribly to the point it wouldn't clear up my acne when it popped up again.

As for the pill, as long as it's not a gel capsule, you can still chop it in half if you feel it's too large to swallow. M&Ms and Skittles are pretty close to the horse-pill range of pill sizes, so trying to swallow those whole to get yourself used to it isn't going to help much.

I know how it feels though; I had to start taking ibuprofin and cold medicines in pill form when I turned twelve and I actually threw up a couple times because the pill would get lodged due to me not swallowing right. That's how I came up with the Water/Drink In Mouth Then Swallow Pill With Head Tilted Backward thing.
