I own my own business and also find myself avoiding work and surfing the net too.....my therapist said it could be ADHD....I tend
to avoid starting projects and procrastanating on everything else...
Klonopin has helped ease the anxiety ....I too am lacking in exercise, overweight and poor diet

the answer?

I dont know, but 2 weeks ago i kicked the computer monitor off my desk and then crushed it with a 16 pound sledge hammer
(please dont do this...makes a terrible mess)

I found without the computer I stayed more focused and did more work.....but I know you use your computer for work

I now have a new monitor

if you see a therpaist talk to her about it..,we just started going down that path
