thought I'd share my experience too as reading through other has helped me so much to not feel so alone.  I quit in July last year and have been through varying depths of hell ever since. Most of the same symptoms as everyone else but the anxiety and gastric issues have been the worst. I was hospitalized in December and diagnosed with Ulcerative Colitis which two different doctors told me is quite common after quitting smoking and unfortunately taking up smoking again won't help at all. The last two days have been almost unbearable with the anxiety being worse than ever. I really don't want to take anxiety Meds but I feel like I am clinging to my sanity with the last few shreds of strength I have left. I feel like I am heading for a mental breakdown and not sure how much more I can take. I don't know what I would do without these posts from everyone as they have really helped me to not feel so alone and isolated and crazy. I have started a Facebook group called Quit smoking feel like c**p if anyone cares to join. Perhaps it will be a nice way to support each other through this horrific time in our lives. Thanks for all your posts.
