Went to the gym for the first time in a couple months or so, same upper body workout I usually do. (I know, I know bad Jkm). It takes about 30 minutes usually, Except about halfway through I got a pukey taste in my mouth and started to feel super hot and slightly lightheaded, nonetheless I still finished it. I chose not to have a scoop protein powder in a jug of water afterwards, since I already had a pukey taste in my mouth. Is this semi normal, anybody else have this happen before?

S4 for your time.
