What do you think about my experience with Adderall? Were my side effects normal?

Background: last spring I was taking 10mg IR adderall very occasionally (maybe every 3-4 weeks) for school usually splitting them up and sometimes taking a whole 10mg with 0 side effects.

Well...a few months ago back in October I started taking more several times a week and had a really bad scare. I drank coffee studying for an exam one night with my adderall and my right arm went completely numb and left face started going numb. i started slurring words and I also could barely move my fingers. i also got cramps/muscle spasms all over my body. It was really terrifying and took me a few days to recover.

After this I was hesitant to try again but i had another really big test so I decided to take it again. This time I drank tons of water and no caffeine. Well it happened again this time on my left side of my body, and this time took me A LOT longer to recover. My left arm was numb for almost 2 months, forearm was in extreme pain, eye twitches. I really thought i messed up my body and did some nerve damage or something.

I talked to my doctor and she brushed it off, didn't think it was the medicine and told me my blood work and nerves are fine. I did always do a lot of nicotine and drink caffeine everytime I have taken adderall since I started. I have now realized thats probably not a good idea.

I decided to take a long break, it's been 3 months now with no adderall and no caffeine. I am also 1 month nicotine free. I finally feel normal again so I was wondering if I should start again but in really small doses???? obviously this time with no nicotine or caffeine ever again. My doctor just said to not take a break and I was fine but I don't know.
