I used to love long steamy hot showers and always felt so miserable afterward for hours, as I was still trying to learn how to manage my heat & cold extremes intolerance. I finally learned to take your type of shower, and making sure it wasn’t hot for long. I also found that taking my shower close to my Gabapentin dosage time helped, as for me, Gabapentin seems to take about an hour to kick in so helps me recover from the shower if I got it too hot.
