Tiredness from speaking?

Tiredness from speaking? I have just recently accepted my stutter.Earlier I used to avoid many speaking situations like talking on the phone,talking to strangers etc.Now that I have accepted my stutter and started talking every chance I get,I am feeling that a chunk of my energy is being wasted?Is it normal to feel exhausted after each talk?Like I have to stop and take a breath after I had a conversation.Is it common for stutterers to feel like this?
