I "kind of" gave up the range. At one of the courses I play there is an eighty yard pitching green between the 1st, 2nd, and 18th holes. I regularly walk out there and work on everything inside 80 yards. I find that hitting partial to full wedges is more beneficial to my full swing than trying to work on things at the driving range. I love hitting knockdown irons shots now because it's the same feel as a partial wedge for me.
Also, I tend to lack focus when the range is crowded. I think it's an anxiety thing but I feel confined when I have people in both stalls next to me.
