Yes. Got a sample of the doctor. I felt like it was getting down into the lungs better, but that could have been wishful thinking too. It is much more expensive then the capsules. I have a lot of the caps still, so I'm back to using them.

Yes. It really works for me, I've been doing it for a little over a year, no side effects that I noticed.

Yes; works just fine.
