I'd suggest Uplinker is correct - try and wind down the number and amount of medication you take in a steady manner.
And anyone on medicinal cannabis had better be very careful where they go and what jobs they do. It may be "legal" at home but it's a minefield elsewhere. I wouldn't want to try and explain the difference in Dubai for example.
In general too many doctors treat symptoms rather than causes - and there is a lot of evidence to show the more different medicines you take the more you are at danger of falls, balance issues etc etc
