mh+, medication
As I've been taking Ritalin (generics) for a while now, I've noticed my preference changing a bit - I now like to slightly "underdose" it, and then spike it up a bit with an occasional cup of tea.
This gives me a bit more of an 'ebb and flow' in my mental state, where I don't *constantly* feel one way or the other, but it can fluctuate a bit between 'relaxed focus' and 'slightly chaotic excitement'.
Really seems to help in continuing to feel like myself with eg. excitement for my own projects, while also giving some much-needed rest from a constantly-chaotic brain... while still mostly preventing brain fog!
