Hi,
I have the bone clicking as well, more specifically it's the joints and where the bones meet. Haven't seen anyone mention it on here before but it is something that concerns me out of all the symptoms as it seems to have gotten worse since onset 4 years ago- did you find it has gotten progressively worse over time?
I got this from x and weed as well. Most of your symptoms sound similar to mine, I think this hppd varies depending on which drug was taken. Also have the music which I agree is very annoying! Will be visiting shrink for the first time next month to try a med possibly, maybe siminet.
This disorder does seem to feed on itself, more you focus on it the more it gets to you and makes you feel negative. I'm battling and figuring out options to wellness at the mo like most people on here. Have given up booze this year and plan on doing at least 6 months, also started eating very healthy and exercise at least 5 times a week and getting proper sleep.
All these things help altho it is tough not drinking- am similar age to you and do enjoy going out drinking which allows you to forget about hppd for a bit and keeps you sociable. But, I'm determined to improve and get better so its gotta be worth a try for 6 months to a year doing all these things (taking good care of yourself) and then seeing how it is in a years time.
Have read a few success stories by people who have recovered through exercise and diet over time. Have read reports on vipassana meditation or just meditation helping which i will try, and also challenging yourself mentally- learning new skills, languages etc.
