I was advised against flying for at least 6 weeks post op, it's due to the air pressure, risk of infection that kind of thing. I had flown first time fornight ago 3 months after the operation and it was fine.
As for driving i was well enough to drive short distances 4 days post op. It depends on individuals, I didn't get any dizzness, sick after my op so i guess i was okay to drive when i was ready. People who were affected by the operation should avoid driving until they feel normal. OK.
I did get stiff neck/jaw for few days hence sugary puddings as it's easier to eat and to help to improve the strength, also overall mood with sugar fix, . There is alternatives jelly i believe or veggie puddings. Other foods that is already pre-made prior to Operation, belive me you don't want to cook soon after the op.
I love vegatable lasagna, this can be made and frozen.
Driving 4 days post op? Wow! I was so dizzy and sick I could barely get off the couch after 4 days. 12 days post op and the dizziness just finally went away. So yes, everyone's different, it's a good idea to prepare for the worst, so in other words, stock up before surgery. Also great advice about prepared foods, pudding, etc. I would've starved!
