Art, Your idea he could have MS is a very plausible one, In fact a very good friend of mine who is quite a well known abstract painter has just been diagnosed with MS at 41 years old. He has nearly lost his sight & appears to be drunk at times even though he is not.

I dont know what to think in DG's case, If he is suffering MS it would have been documented. I tend to think he's hammering the booze & god knows what else.
