So I'm curious about something. I know that meds like anti-depressants and stimulants can mimic the symptoms of BPD. But do these things have a GREATER effect on somebody who is on the bipolar spectrum versus somebody who is not at all? Let's take a stimulant like caffeine for example (somebody alluded to this in an earlier thread). I know people who drink coffee all day and it doesn't seem to do anything. But for me.. I'm an instant spaz. But not all of the time. Sometimes it doesn't seem to do anything... but some days.. Feeling Good days: Spaz.
