You'll get used to it... but go to a Big Lots! store and see if they have any of those USB Mouses for laptops they were selling for $5.99... tiny, two button, with a scroll wheel... works great and easy to carry with your Macbook. Voila! No more withdrawal! ;^)>
You can also do what I did... go to System Preferences and set the track pad for two fingers = right click.
Not a deal-breaker, just behavior modification.
Say, though, I actually have a more annoying interface problem: mouse ballistics. I’m physically sliding the mouse ten inches at a time. Customizable, perhaps?
