It's pretty ironic, but helpful, that this has happened during my final project on technology dependency. I went three days without my phone as if I took a mini detox from it. The experience wasn't as bad as thought, but that could have been because I was still able to communicate with people through my Facebook (I wasn't going to go without that too. With my phone, I had no choice).
At first, I felt a little empty because my phone is always in my hand. I have a Droid Incredible, so it's as if I have a mini computer at me at all times. After the first couple hours I felt this way, but I took it a lot better as the days progressed. I surprised myself. I stopped thinking about having the phone with me at all times.
Once my new phone came in 3 days later, I was in no rush to activate it. I don't think I would ever want to give up my phone if I had the choice to. Three days being forced is enough time for me to be without it. Haha.
