Hi, I’m in Australia and I was diagnosed with ADHD a few years ago and tried both Ritalin and Dexamphetamine. Ritalin wasn’t quite right for me either but was amazing in the beginning, I still have fond memories of how slow my brain felt the first few days.
Dexamphetamine was a horrible experience for me personally, I couldn’t sleep and when I finally did sleep for a few hours I dreamt of being awake. I was more irritable than usual and became paranoid and anxious. No anger outbursts but I wasn’t on it for very long.
After a few tweaks to the Ritalin dosage that also weren’t quite right I ended up annoyed with the whole process and (typical for me) stopped seeing the psychiatrist. Instead I worked on getting regular exercise and doing some sort of meditation each day. It wasn’t perfect but was helping, but now am considering a change in routine again…
