Hi GettingClean! 4 days is a really good start. I still felt lousy at 4 days, too. Not so much the anxiety anymore, but my hands still had a little tremor, NO energy whatsoever, headache, irritable, and very little sleep. Looking back from day 11 now, however, I can see a steady improvement each day. So remember, we have nowhere to go but up!! You've gotten through the worst, so give yourself a big thumbs up. You can do it.!!
