have u tried N-acetyltene (600mg- 3 times a day) iinstead of perfenodone. what dosage is azathropine (use 50mg/ daily).
there are no side effects from N-acetyltene. also very cheap to get.
perfonodone is no more better than a placebo.
not aware of any reversible therapies, only anti-oxidant supplements.
enzyme therapy may be possible in future
