I am not aware of any capsules. The psyllium husks that I purchase come in a bag (looks a little like cream of wheat) and I measure 1 Tablespoon of this with 1 T of liquid Bentonite in a large glass of water, whisk and drink immediately.
(Funny, after I posted that last message to you, I was doing my usual reading on the forums and someone suggested leaving the P&B mixture for 15 minutes and then drinking it because it was easier. Bleccch. To each his own, but when it solidifies I would think it would be like drinking wallpaper paste.)
Hey, and don't worry about being apprehensive. We all have our "phobias". Gosh, it took me over 6 months to get up the nerve to do a Liver Flush because some people talked about getting nauseous and that really scared me. I HATE being nauseous.
So, as I said, I really can't see you having a problem swallowing the P&B as long as you don't let the stuff start to gel. And if you mix it well, there shouldn't be any lumps so nothing to get stuck.
