You are not being 'negative' at ALL! You are frustrated and this is why we need each other!!
Let's see how your appt goes.....I hope they don't make you feel rushed. They better take as much time as it needs because Fiona gave very good input and i just KNOW that there has to be a way they can program it the way you are wanting/needing....! That's why there are all the electrodes and combinations of tricks and treats.....

That back pain you describe sounds EXACTLY like what I feel!
Can't stoop, or I'm a gonner.

Oh how I hope you come away from your appointment with a big grin!!!
