GBS and time…
GBS has a “healing time” of it’s own. However, the fact that your dad has the ability to help himself into a car, visit people and go places in such a short time is very positive…plus he did not require a tracheotomy and ventilator. So, in reality, your father is 4-6 months ahead of many other patients. Your father needs to have faith, keep a positive attitude, high spirits, and he already has family support. A positive attitude with spiritual and family love, heals, protects, and restores health more than anything else on this Earth.
Some vitamin supplements I would recommend are: Fishoil 1500mg/day (omega-3 for the myelin sheath); vitamin B-12 (Methylcobalamin lozenge type) 2000mcg/day; vitamin B Complex. B vitamins for the cells/nerves.
