Quit drinking, smoking and basically am living the sober life now.
Started getting a strange metallic taste in my mouth like iron for the past few weeks since quitting.
My stress levels are pretty bad an I notice the taste when it is bad.
Currently on Lexapro 20mg and klonopin .5mg 

Is this just stress? 

I've been working out a lot lately an take a weight gainer with creatine in it as well.

Also noticed one of my teeth are really sensitive to the touch so there's a lot of factors playing in here. 

Thinking about going up to emergency for some blood work tomorrow morning.

Anyone have any ideas though?
