I'm diagnosed with BPD. I thought my reaction to coffee was like everyone else. One of the things that happens is I become abnormally talkative and message and call everyone I know oversharing every detail of my life even though I'm usually an introvert. I spend money I don't have. I furiously smoke a whole pack. I post a tonne of stuff on social media. When I come off the "high" I feel terrible about all of it. After asking several people if they have a similar reaction to coffee, literally none of them knew what I was talking about. They all only said they feel more energetic that's all. 

I'm planning on decreasing coffee anyway, but just wondering if this sounds familiar to anyone.
