Boofed methylphenidate and thinking to do it again

Some of u have prolly seen but I had a post before on this same subreddit ab this. Anyways some shit happened and I thought I was gonna overdose on 50mg extended release pills. I am chill now and sober but am kinda bored and want to try it again, is there a reason not to or will it harm me not to? I have adhd if that changes anything. I probably won’t try anything till I get responses. I should note I was previously on dextroamphetamine for a few years and reached a peak dosage of 30mg but it wouldn’t do much anyways.
