Hey there. I've been under treatment for 2+ years with one psychiatrist and with a second one for some months. So far, no I've had no big improvements over my DP even though the second one is confident that he'll cure me since he's had experience with people exactly like me (and maybe you). He worked with either drug induced dp and trauma-induced (i know drug abuse leads to trauma so they're technically the same, but I digress) patients, which gave me much needed confidence when i first started my treatment. Where are you located? I can point you to the second one, I think he also does online sessions, but I'm not sure. I can ask if you can't meet him in person. All the best.
