Do I need to up my dose?

So I'm on 20mg, have been for a couple weeks and at first I really felt it, I had energy my mood was better, I was able to focus, things all around just felt easier.. the only side effects I had was slightly higher blood pressure, I'm on a BP med already and we added propranolol and it's been under control ever since. Well now the past few days when I take my med I don't feel anything different? Like I'm still kinda focusing on things (going through hyper focus phases) but my energy levels are back down some, my thoughts are still a little racey, I don't feel that initial feeling I use to get when it kicked in... The issue is I don't know how this is suppose to work! Like I'm supposed to get to a point where I don't "feel it" right? It's supposed to feel like nothing and just be my norm I would assume .. I guess I just don't really understand how people without ADHD feel so idk what I'm aiming for here and how to know if I need a higher dose or if I'm in a good place..

I hope at least some of that made sense cause I'm not sure how else to explain it lol.
