Being out of our element (traveling) can mean a return to addictive behavior. I know whenever my family and I go on vacation, I always seem to binge a day before we leave. I'm not sure if it's because of stress or whatever, but I've done that the last 3 trips. I always feel great during the vacations, but once we get back I know it's been 4 or 5 days since my last binge. That's when the withdrawal starts to set in. Don't get down on yourself. It's good that you returned to your reading material. Are you counting this as a relapse? Did you watch true porn or just porn substitutes like YouTube? How long did you act out? I know you mentioned this trip will be a lengthy one (I think?), let's use that as fuel going into the weekend and a running start for when you return. Good luck brother!!
