Smokers always can tell because cigarettes taste sweet. You are getting the symptoms of metal fever. We were always told back in the day to drink milk. Key thing to remember is this IS A DEHYDRATION ISSUE!!! Drink water and juices (don't want to get an electrolyte imbalance) and drink some more. You will sweat, you will have chills, you may even tremmor (I did).
Probably feel exhausted in the morning but should be OK.
I got it from welding on improperly cleaned hot dipped galvanized and ran a 104 fever. That was in 1976. It NEVER happened again!!!
