Hi Cas, I'm finishing up my PhD in Creative Writing (submitted at Easter, slow to get reports back, now waiting to find out what last edits needed) - and I have to report my frustration with my brain power per writing for at least the week following each infusion (I've just had my 4th). I tried but struggled each time. In my working weeks (2 out of the 3) I edit postgrad and colleagues' writing, and it can still get tricky with fatigue finding the right words & expression. I was due to take part in a Masterclass writing for a new novel but following advice I've delayed till April, and that should be a month from the end of my radio. That being said, I have taken up a class in German, though I confess to not doing much homework...
