I think I did have to some extent, but I thought it was only when I was really anxious. I thought I could control it in public, besides I tend to hide away when I am really anxious.
But recently at a work social gathering I didn't notice, but somebody pointed out that to me. The thing is at this stage I have had a few drinks and I though I was relatively comfortable with the situation, but I suppose subconsciously I maybe was quite stressed & anxious. Now I am wondering if I get it even when I am not anxious/stressed (like at home), hmm maybe I got some other problems.
