Thank you, all

This has been very informative and helpful. Yes, the doctors usually caveat expectations with "everyone reacts differently" but when I talk about all the driving, the randomness, the urgent requests from my clients - they council that my company needs to find some sort of replacement for me realistically.

I'll try my honest best to be useful (if nothing else to fight the boredom if I'm feeling well enough) but it definitely sounds like driving (after the 'badness' sets in ~ on average after 2 or 3 weeks until I'm full recovered enough to not be nauseous or on pain meds) is a non-starter.

So far all the doctors, nurses and office managers have been fantastic. I feel like I'll be in good hands. I'm sort of itching for it to start (in the 'sooner begun, sooner done' vein) but I'm also a nervous wreck.
