I think that it is definitely worth trying it - I had a lot of problems feeding my first, he didn't latch properly and I let him feed anyway and ended up with cracked and bleeding nipples, a couple of doses of mastitus and finished with thrush inside my boobs which was the most painful thing ever! I ended up giving up completely at about 5 and a half weeks - I was miserable, in pain and stressed and in the end I thought that that was worse of for my baby than not being breast fed. My second was absolutely fine, latched on straight away and I had none of the problems I had with my first. The only problem was then trying to wean him off again and getting him to take a bottle!
What I am trying to say is that definitely try it, take all the help you can get, but in the end if it doesn't work for you, don't beat yourself up about it.
The convenience factor is a real bonus - the amount of time you have to spend washing & sterilising bottles and making up feeds when you could be sitting just relaxing and feeding. You always have breast milk with you, it is always the right temperature and if the baby doesn't finish it, you don't need to throw any away! It doesn't cost anything and as an extra bonus you lose all your extra baby weight really fast.
Good Luck with what ever you decide.
