not sure its right place to ask this...
do i overtrain or something? or am i thinking too much?

yesterday i trained my back alot...8reps,8weightplate(add 2 more from previous)(10kg/10LBS increase),since they are some stupid guy keep rushing us for the machine,resting time was about 40sec...arm and bicep exercises,deadlift almost 50-60kg for 6 reps(10-15kg previous weight)(pretty hardcore for me),7-8 exercises in total...

and when i go to sleep,everything was fine,until i dream that i was drinking too much liquor(i know it's weird),and i woke up and vomit instantly(luckily there was a dustbin beside my bed),after finish throw up,drank some water and continue to sleep afterward,and today i felt like shit no appetite to eat,but i still able to force myself to eat some bread...

so what you guys think from your experience? food poison or overtrain?
i ate 2 healthy meal at home,1 at the outside(nasi goreng pataya+1 kerang bakar only),not sure i allegic to kerang or not,cuz i never ate kerang for a very long time...and no,i do not consume any alcohol in a week...

was thinking too much,food poisoning is what i thought too,cuz yesterday was more intensive than that day
thanks reply anyway...
