That’s good! And it is a good approach to try one thing at a time. Soaking hay really makes a difference for my guy and usually negates the need for meds.
I like my Flexineb because it is easily portable, doesn’t require an outlet, the horse can be walked with it on, etc. They usually have a 10% off sale a few times a year (at/around certain holidays). So if you ever want one, you can try to save a bit. They’re expensive, but worth it, IMO.
