Well make sure you tell him everything, if anything he will hopefully reduce the amount of meds he gives, I only ever get a week at a time because of my history at least then there will be less risk of you doing the same again

Healthwise I'm not sure. Have the twitches got worse since the OD and the headaches? I know you said you had a blood test after the OD but if they were testing for other things maybe they wouldn't be looking for other damage. It might be worth mentioning that and going to the hospital to get yourself properly checked out if things still aren't improving.

Other than that I guess you gotta stay strong, keep getting tests done and find out what is actually wrong with you so they can treat you for it.
