After reading your query it seems that chtonic alcholism
smoking and
diabetes has affected the nerves.
if the nerves are denervated or damaged such problems can occur.
I would suggest if the dr has checked the
muscle tone.
Also whether there are no other conditions like
vertigo or
postural hypotension ie when the person get up he has giddiness or looses balance.
The good thing is since the CT has came normal there are less possiblity of other pathological conditions.
I would also suugest to get his electrolytes values checked. Sometimes electrolytes imbalance does give rise to such symptoms
As Far as homoeopathy is concernde there are good drugs like conium, Gelsemium, Ambra Grasia, causticum which will help in such cases.
I would suggest to consult a homoeopath who will take a detail case history and would prescribe drug as per his symptoms.
I do not reccomend to take over the counter medicine without counsulting a doctor as the curability will be doubtful.
Yes homoeopathy will help to resotre his health
