does anyone know for a fact is it possible to be physically addicted to exercise so that u actually have withdrawal symptoms like i mentioned above? perhaps it hasnt been proven scientifically yet, i dont know. but it sure feels like this is what i have.

also, now i find that when i work out, i dont get the same high i used to. i do feel less down if i went in down, i come out better, but its not as strong as it used to be, its like ive built up a tolerance of sorts. but im nearly 40 now, and i cant really work out harder than i am already - i feel quite tired after a hard work out these days.

any advice or knowledge about exercise addiction please reply if u can.
