Colleen so glad you have got a date.....brilliant news
I have mine on my left side...Im righthanded also....so I find it much easier to hold the controller over the battery with my left hand and control the controller with my right hand. Plus I much prefer to sleep on my right side (although I mostly sleep on my back) which to me is much more important

.......
Im sure you will get it right no matter where it goes, at least you are getting it!!!!!........
