The best thing you could do is find a teacher who is an expert on embochure mechanics. Having someone in person to guide you along is huge here.
Speaking of huge, embochure changes are HUGE DEALS. I have been there, myself. I went from a far right, very low embochure to a centered(esque) farkas. I was an extreme case of bizarre embochure needing sorting out.
I went through an embochure change my Freshman year of college, two years ago New Year's Day. The first thing I played was the trumpet riff on that old show "Highway to Heaven." It was like starting over on the trumpet. I was horrified.
It took me roughly six months to get stuff in decent order for playing. It took about a year and a half to get to where I was before the change, and even now I am about a year behind where I should be (God help me, it still feels like I'm rolling a boulder uphill sometimes).
Still, the progress and improvement in playing and sound is astounding. I can do a lot more than what I used to; I can play higher, longer, just better. I can get as bright as a G bugle, and as broad and vibrant as a C.... I love the bugle sound, personally.
Joe, this is a huge thing. Everything changes. Maybe a little or maybe a lot, but everything changes. How you tongue a note, how you control the note, how you hit the note, air flow, everything. You better be ready to put at least six months into the woodshed, bare minimum. And be prepared to suck. A lot.
