Despite of being quick witted, I was always quite shy. With a lot of work I started getting better when it comes to social interactions, became confident and learned to like who I am. Still when i go on a date, or even just meet with my friends I have that stressful 20-30min at the beginning. It's quite bad i feel cold and shaky, and have to force myslef to talk. When it goes away after a while, I can dominate my social group, but I think that sudden change has to look stupid. So my question is - how do you warm up? Also alcohol is out of the question, I'm interested in self development, not temporary solutions.

PS. Sorry for my bad english
