Hadders

I know this is a very old post but has anyone found help to this problem as I am suffering with close to same problem here for past 3/4 years. I use to do powerlifting regularly until one time I got muscle spasms and felt completely overstimulated and stayed with me On/off since. whenever i incorporate exercise I feel bad for days no sleep, caffeine makes me feel sick & Get random body shakes. currently on diazepam at moment only 2mg which helps with anxiety but everything else is still there. Know it’s old post but Any kind of advice would be much appreciated
