why did 4mmc work so strangely for me

yesterday i tried 4mmc for the first time. i took about 200mg in the span of 2 hours - i started slowly because i wanted to be careful with the dosing. i snorted most of it in multiple, small lines and it didnt bring me any effects. then, i dissolved the rest of it (about 60-70mg??) in water and drank it. i could sense something is different after snorting the last line, but it wasn't enough to even feel a small high. after about 15 to 30 minutes of drinking what was left, i started to feel something more. i was somewhat relaxed and was lying on my bed. when i was getting up to drink something or blow my nose, i wasnt feeling any of the effects. to summarise, the effects of that dose for me were: relaxation, music appreciation enhancement (only a bit) and i was feeling a nice tension in my legs which made me move them all the time and tense the muscles in my legs - it felt nice. i felt a small bit of euphoria, but it was mostly just relaxation of my mind and body. my pupils were the same as when im sober. how come this happened? i know the high wouldnt be very intense judging by how long it took me to take everything, but isn't it still strange? if that's important, i have a suspicion of ADHD, although i didn't get diagnosed yet.

i also took mdma 3 times in the recent past - about 200-260mg each time. it worked similarly for me - my muscles were relaxed causing me to move my legs the same way as with 4mmc, i felt more comfortable in my body, my mind was relaxed and i was a bit euphoric and i didn't feel the need to sleep. nothing else. from what i know mdma is a different type of stimulant and that it's sometimes more relaxing to people, but it's still strange that both mdma and 4mmc worked on me this way. any ideas on why i react like this to stimulants?
