Hi John,
Has the low animal protein diet been explained to you?
If not ask your neuro so you know it's not just me giving you an alternative health idea.
Plant protein is ok but try and lower your intake of meat and dairy products etc.
Also meds on an empty stomach work a lot faster plus by then giving it say 1/2 an hr to do its job that can make a difference to the length of your ons.
There's always DBS when things start to look a bit grim so hang in there!
