Put all the great advice from this thread into action and repotted to a smaller pot with a cactus/succulent soil. I removed the old soil from the roots (lost some roots on the way obviously but I understand this is fine) and watered one day after repotting (soaked it until water came out of the holes and left it in the sink until it stopped draining). So far so good and the plant looks healthy, however, I notice the leaves seem to be REALLY curly? Looking at other Dracaena Burley pictures it seems ok, but I'm no expert - what do you think? It's been a week since I repotted (can use the previous pics as a reference):
Also, if it matters, I moved it to a new location (this way the snake plant also gets some sun):
