Does PEM ever go away? My experience.

Im really asking myself the question sometimes does PEM go away? Currently i am in a very very bad crash after going out for drinks and helping a friend move all day the next day.

Tbh i have to say my PEM got way better in my past 1,5 years having LC. I recover from crashes within days instead of weeks. Working out is still hard, i can do some cardio tho. Weightlifting (which i love to most) is practically impossible.

I’ve heard on this forum, PEM keeps getting better and better for most haulers after 1 year or more. And that is what I experience after using Nattokinase especially. I just ordered electrolytes, to see what that does for me. What are your thoughts?

Does it ever fully go away and what are current researches on it?
