I wouldn't gauge the tetra effects on this example only, as your situation prior to taking it wasn't normal. It might be fine once you're on a good diet and regulation cycle.

High protein in known for binding.

You need EFA essential fatty acids and that will solve your problems, I'm pretty sure. You can buy them in capsule form for good strengths.

Otherwise, be sure to use a good oil like olive oil, a teaspoonful a day...

and of course cold water salmon is an excellent resource too.

I'm amazed to learn that someone with nearly no stomach can become bound up this way.

Hope you find a solution soon that works well for you.
