Whilst I only take coke very occasionally nowadays, I am constantly reminded by my heart what it felt like to take it. I read somewhere that when a person thinks of coke, the rhythm of their heartbeat changes and since then, I have been monitoring my rhythm and any other signs that the coke might have disrupted my insides which is probably not a good way to be looking at it. I'm sure most of these will be mental, but is that the most damaging? Because there is a strong connection between brain and heart, albeit subconscious, and I'm slightly worried that I am thinking about it too much, or worse, something did go wrong. But generally because on two occasions I took too much and will probably never forget that experience because of it. I understand that some people are doing maybe 4 times the amount that I did but I can't help noticing every tiny jump my heart makes now. I guess it's the feeling that I have lost some control over this that I used to have. I'd welcome any thoughts on this for those of you who have been through a similar scare or who don't consider it an issue.
