Sometimes I just leave my house without my phone, and I don’t really care. This is a new development. I used to find it very stressful if I accidentally (rarely) left my phone behind.
A couple of times, it has been truly frustrating to not have my phone so that I could access my email.
Mostly, it has just highlighted for me how useless the phone seems to me without that feature.
However, rather than making me want to run out and get a phone that I can get email on, it mostly makes me think about getting rid of my phone entirely.
So, yes, I was very addicted to my smart phone, but so far any withdrawal symptoms have been minimal, at worst, or possibly just nonexistent.
