If you are having a PLANNED CS you should bear in mind that it is generally a much easier, calmer procedure than an EMCS, for a start.
There is no physiological reason why Bf should be harder after a planned CS than a simple VB. The drugs used for anaesthesia (spinal or epidural) are MUCH less likely to have any effect on your baby than other anaesthesia as they don't cross the placenta. The one drug you really want to avoid in terms of successful bf is pethidine. it is an opiate which makes babies sleepy after birth and harder for them to latch on and bf.
If you have a 'shivery' reaction to the anaesthesia, or throw up, obvs that will make holding and feeding your baby a bit harder immediately afterwards, but those effects if you are unlucky enough to get them shouldn't last long.
Bear in mind that women who have EMCS's tend to have gone through labour beforehand, sometimes a long labour and are generally knackered and have other drugs in their system before they get as far as a CS.
There is no reason why you would bleed more after a CS (who is giving you this info, btw? They sound quite alarmist!). My consultant told me I was likely to have a lighter bleed but it might go on for a bit longer. I'm not sure why this would be true, but I bled medium to light for about 4 weeks.
The 6 weeks driving 'ban' is largely a myth. Check with your insurers but usually you can drive as soon as you feel you are ready. (When I rang my insurers to check I was allowed to drive, they were baffled - they pointed out that people have surgery for various things all the time! and there's no 'ban' on when they can drive, it's up to individuals to be sensible. If you feel no pain and are strong enough to do an emergency stop then you should be fine. Obviously you can leave it for as long as you like if you have support).
My best tips for CS recovery are:- peppermint oil capsules in case you get trapped wind - a large refillable water bottle with a sports type cap so you can keep a lot of water to hand and drink while you are breastfeeding! and get a big V shaped cushion to prop you up afterwards. John Lewis do a fab one.
Keep on top of your painkillers and you should be fine. I had my stitches out on day 5 and felt pretty good by then - just the kind of 'soreness' you get if you do a lot of sit ups. I had to be careful getting the buggy up and down kerbs, making sure I didn't lift it, but that wasn't too hard.
Good luck - I am sure you will be totally fine, esp if you have family support to fetch and carry for you.
