I’m not looking for medical advice, but more understanding. I have chronic back pain. I can alleviate it completely with only 2 things - alcohol and a heating pad. Ibuprofen lessens it but it’s still present. Muscle relaxers do nothing (which makes sense because it’s not muscle related, it’s spinal disk degeneration).
A tall glass of whiskey makes my back relax and I can move normally. Once it wears off tho, it’s right back to tense and painful.
The article you linked states that many people have trouble sleeping if they do exercise before going to bed, because the physiological response of doing exercise activates the body in a way that makes it harder to sleep for a while and recommend doing it a couple of hours before.
