ok a couple of weeks ago.. i went early in the morning.. drank glass of water.. went to the gym.. (hadnt worked out for a long time or did any exercises) I started to lift weights.. then I felt all exhausted and felt like i was gonna faint.. i kept using the machines.. then i felt like i was gonna puke.. i went go to lie down and went home.. this has happened to me 3 times in the past.. i think its because im not in shape.. today before I went i drank 2 glasses of water.. and brought a gatorade to the gym.. I didnt feel sick anymore.. but that was because of all the water i drank.. why is this? my friend doesnt need any water and hes fine.. well obviously cuz hes healthier...
