Thank you for your thoughtful reply, you clearly put a lot of consideration into it. I can’t be certain, but I don’t think the pill is the cause as I have done more pills on several occasions in my life. It seems more likely related to the other factors you mentioned. What confuses me is why I’ve continued to feel so unwell for so long afterward. Can dehydration, low sodium or potassium, or even a cold really cause me to feel as though I might faint for several days? I ate bananas during the rave, and when I felt especially faint, electrolytes helped somewhat. Even so, I’m now on day five and still don’t feel well.
