I don't know if I have ADHD, but I struggle with this as well! Sometimes I'll write a message/email and there's a paren after every other sentence.
Lately I've been making an effort to substitute with a semicolon or bridge the thoughts with a dash:
"I'm thinking this - but I also think this."
Unsure if that's a correct usage of punctuation, but I feel like it helps the sentence feel more focused and an expansion of the thought, rather than a random segue (especially with work)
Edit: realized that I had broken my own rule seconds after posting
I consider second shift to be worse - I worked 3-11 for awhile and its just depressing. You wake up and can do things, but you're just waiting to go to work. When you get out, it's pretty late and most people are going to bed.
9-5 allows me to have my relaxation time at the end of the day, along with everyone else. Any other shift feels lonely, and like you're off-sync from the rest of society.
