I definitely don’t have the part pre-medications, and I have the caffeine jitters only sometimes - less than once a week. I’m taking concerta for reference.
I’m very curious about the pre-medication jitters. It feels to me more like anxiety/anticipation than a symptom of medication. What happens if you delay taking medications after you start thinking about it? What do you associate with taking medications? Do you start working or “being in focused mode” right away? I tend to get more jitters if I “need” my meds to be effective soon vs having a bit more time for them to activate fully.
They never tested me, but the advice was to not “combine drugs”. They also asked questions to make sure I was not addicted to anything. ADHDers have a higher % of substance abuse, so there’s that.
In my opinion it’s always better to test treatments in the “cleanest” state possible, so you know better how the medicine works. ADHD medications also take some testing to understand what’s “best”. I ended up naturally avoiding coffee too (I didn’t need it anymore)
The way the posed the testing though, it seems either a requirement from insurance or the specific clinic or the country you are in.
