Shooterman – haven't had as extreme a situation but was ready to inflict some very serious and permanent damage on my boss 18 months ago, who clearly deserved it, but I took a step back which was lucky for both I suppose! I cut out alcohol and caffeine (drinking over 25 espresso's a day is not a good idea – had done it for years and worked out I wasn't always as stressed as I thought I was!).
Try some reflexology or some acupuncture for relaxation – I started doing Iyengar yoga too and it really helps. I also liked the rather attractive and awfully supple ladies in skimpy clothing.
Good luck with it – you're not alone – but I'd suggest that medication and a GP won't sort the problems sadly.
