Starting Meds and I don’t know how I’m supposed to feel on them?

So I got diagnosed and after a bunch of crap with doctors I finally went on meds. I chose to start with Ritalin IR 10 mg twice a day as needed. I wanted as needed because I’m a SAHM so I don’t need to be focused all the time. Just on days I need to get a lot of housework done or the 1 day a month I go to work.

So I started with 5mg and it quieted my brain. Awesome. After taking it once or twice I found myself still falling into my distraction/avoidance of various household chore routine lol. So I went up to 10mg. First dose worked well, was able to do stuff etc. It made me pretty sweaty and I’m not a sweaty person lol Doses 2 and 3 on different days seemed to work less well. Still a little sweaty, and then I started yawning? like a hour after taking it. And again started distraction/avoidance. So I went up to 15mg, and a couple doses in and the cycle continues and I started yawning an hour later, less focus etc.

I read that your body gets used to the side effects as you keep taking it, but I take it infrequently. I got 28 pills (a 14day supply) 3 weeks ago and still have like 15 pills lol

How do I know what I’m supposed to feel like, or if it’s actually working and I’m not just somehow placeboing myself into focusing? Or if I need to change drugs? Or increase dose? please help I feel stupid
