well, not every, but a lot...
e.g. i get panic attacks, dizziness, heart palpitations, asthma attacks, inability to think straight and the like from being in a new situation or being overstimulated by noise (ie industrial noise, not loud music) .
i get irritable guts either from stress/anxiety and/or something in my diet (pretty sure it's dairy or glucose)
but lately(well, over the last few years), i've been having periods of low energy, low self esteem, depression for hours or even days at a time when i have the most horrible thoughts when suddenly BLAMMMO!! ! it lifts and i have this great new idea for my website so im up for 3 days straight writing javascript then out to the pub and working at a gig and getting absolutely wasted and going to heavy rock gigs and clubs and deafening myself and never wanting sleep, and then getting home again and "inverting" and crashing out and not wanting to be near anyone (less so than normal)...
