I am experiencing the same feelings today of rapid heartbeat, sweating, fighting the urge to cry. Today is Day 6 for me. I haven't gone a week st8 in over 3 years. Just wanted to say I'm with you. Coming on this site has helped some. Sleeping most of day helped some. Knowing I will be going to a meeting later helps. Doesn't make it any easier but I know this will pass someday and nothing is worse than the damage i've done. No need to add to that!!
