I exclusively bf my second dc for 23 months after bottle feeding my first (long nicu stay) and if you can get past the first few weeks, it really is the easier option in my opinion. No sterilising, constant supply of milk weather your out for 5 mins or 5 hours, great excuse for lazy skin to skin days.
I did try combi feeding but unfortunately left it too late and dc had complete bottle refusal gave up trying in the end as it was stressing us both out.
Few tips...
Get a good nipple cream and apply every time your arms are free
Make sure you get a good latch established before leaving hospitals, there are people to support and it makes all the difference
Research different feeding positions can help with both latch, pain and exhaustion (prevent dowsing on the sofa while feeding if you can master feeding lying down in a safe environment)
Find a breastfeeding support group - this could be on organised group or just a friend that has done it before who will no doubt have many hints and tips
Make sure you have a supportive dp. Many times in the early weeks I wanted to give up but his support kept me going, snacks, warm baths, massaging clogged ducts 
And finally I'm still a believer even after 23 months that fed is best and the mh of mum far outways the benefits of breastfeeding. It's the hardest but most rewarding job if it works but don't feel like a failure if both you and baby can't master it. Just as you are learning to feed so are they.
