What you describe in the first post is actually why I got off Celexa and turned to cannabis for my own panic/anxiety issues. Even a very low dose of Celexa made me so non-confrontational that I ended up not making issues of things that should have been discussed.
The thing that I like about cannabis as a replacement for my pharmaceutical anxiety med is that it is very simple to dose myself to a level that I would consider to be sub-recreational but definitely keeps the anxiety level down. As other posters have said, keeping a cool head can actually PROTECT you in many situations, so finding the point at which you are not likely to OVER-react, yet still can REACT, is the key.
