Been finally doing 3x15s of 10 second eccentrics everyday for ~3 weeks now in addition to foam rolling and stretching and wearing the Achilles strap when possible. I've gained some strength for sure, pain is decreased, and the bump on my Achilles has definitely gone down.
Mornings are definitely never perfect, though. I bought a $30 night splint at Wallgreens yesterday and I'll see what that does. Felt pretty good this morning. Not the usual struggle to get it up to speed.
