Hey Afortunado,
Work-wise: I wasn't affected at all. when I did my first leg, I took Paracetamol for the 5 weeks at night only before bed, so I got my full sleep. During the workday, with few cups of coffee ( i love my coffee), I was working as normal and lol you forget you are even doing LL and find it crazy how you are, and no one around you knows. Then eventually, I think it was week 6, I wasn't even taking paracetamol before bed.
Work was a great distraction for me and going to work forced me to get up and be productive and walk which is important for consolidation. Being able to go work, and working at a high level was the only reason I did one leg.
Travelling wise, for the first leg, when i booked my flight,I requested assistance, so soon i checked in, I was wheel-chaired pretty much the whole time. they take you through all the priority lane, skip all ques and lol I did feel awkward and pride made me feel embarrassed but it was necessary. This time, I didn't need the wheelchair, but still informed them I was on crutches and this allowed me to use different que for security clearance and not use the stairs on the plane.
when I did my first leg: walking wise, the first month, maybe up to 0.5K with crutches, following month I increased a lot! Then soon as the lengthening stopped, the very next week I was walking long distance no crutches.
Now that i am doing my second leg, very different progress, as it feels much easier and only took those 7 days off for work when i was in hospital, did few days remotely and as i mentioned above, going into the office tomorrow (18 days since i did surgery).
My mistakes:
-My weight, I was 14 stone when i started and didn't do any upper body training before the surgery.
However, i did adapt, the upper body did become much stronger, and the non-operated leg became super strong. but I would strongly recommend be light as possible, and have good upper body strength, resistance training where you are using your body weight as oppose to bench press. This will make being on crutches much easier. Walk much as possible once you done the surgery where you are using the operated leg,this will help alot with consolidation.
