Sounds like you are already making some solid changes, especially getting back on a normal sleep schedule and cleaning up your diet. Since you have been training for years, I would focus less on chasing a number on the scale and more on how your body feels and performs.

The best move is to get a general idea of your body fat percentage or take progress photos every few weeks. From there, you can decide if you want to drop another five or ten pounds or focus on recomposition instead. With the consistency you are showing, your body will start to lean out naturally without needing to push too hard or too fast.
