I did a week-long hike in the Los Padres national forest about a year ago. It definitely took a few days to get used to having no communication. (I still reached in my pocket to check my non-existent phone once every half-hour like clockwork). The first 24 hours were nerve-wracking, all I could think about was "what if something crazy happens and nobody can reach me?". But after a few days I just forgot about it, the internet just wasn't something that crossed my mind.
