Just curious is all. :)

Have you always had the same reaction (good/bad) to caffeine? Has it changed?

Has being on certain meds changed your ability to handle caffeine without becoming mentally unwell or getting too productive?

For me, when I was younger - before my bipolar disorder progressed, I was able to have caffeine no-problem. Now, it makes me feel extremely mentally unwell. I'm 35 F for reference.
