Oh how i love my tablet. I am a tablet advocate! Wacom should love me because i am always promoting them!
I had intense pain in my wrist from doing graphic design and just surfing the web with my mouse all the time. It was so bad, It would bring me to tears. After 4 months of thinking that i was going to have to quit graphic designing, My DH ordered me a Wacom.
Life changed after only a few days, I put away my mouse and made myself use the tablet exclusively. Pain totally went away.
I now use my tablet for everything, most of the time, i don't touch the mouse at all over the course of a day.
Although, i do know a lot of people who have tablets but, never use them, they are just sitting in a corner

So sad but, you do have to be committed to making the change. You WILL get used to it. Even if it feels really strange at first!
