Hello, just a little observation, if I may? Your meaning is clear in your original statement. However, you might want to limit the number of references to yourself in that one statement. Instead of 3 references to yourself, you can reduce it to 2: "I try to do these things to perk myself up." Hope that helps.

There are some ways to perk yourself up when you feel drowsy. I myself try to do these things to perk me up. (Would be the correct way)
