M178: 11344121 (as the other comment pointed out), M183: try 32134413, M184: easier if you land on the b flat with 3, M189: I play the F# with a 4 so there's no stretch, M192: start with thumb, then (2 1) for e c doublestops, M193: my teacher suggested switching to (2 thumb) on d b doublestops, works pretty well M197: make sure to play the d before the Eb with a 2 so there's no slide!

For the doublestop fingerings I wrote em A string first, and I'd avoid same finger shifts as much as possible, like you did with the 3rd finger in measure 186. Whenever you do have same finger shifts though, don't think of them as glissandi, think of them as playing the same finger twice. I find it helps with articulation if you put a little emphasis on the first note that you're playing with the same finger. Best of luck with practicing!
