I got home from work at about 8 this morning after having about 2 hours sleep in 48 hours and working 26 of 35 hours, feeling like death. My chest was burning and it felt like something was squeezing my heart. I get to bed and just couldn't sleep till about 11 ish and even then it was only for 3 hours and nw i feel like crap still and want to go to sleep but cant.

Does anyone have any tips?
