I know what you are going through and I'm sure other people will write in and tell you they have been there too. I know so many people who talk about that 6 week mark that signifies the magical transition into smooth, routine breastfeeding - but it is not always the case. I think, from my experience, that breastfed babies and their Mums often take up to 12 weeks to really get into any pattern. So many people give up at the six week mark when it really does improve, often, only a few weeks later. Of course there are many instances where a woman may change to bottle feeding, but if you are not experiencing supply problems or attachment/nipple problems I would encourage you to perservere a bit longer. Breastmilk is digested much more quickly than formula. Formula fed babies are fuller for longer as the formula takes longer to digest. Breastfed babies are going to need more frequent feeds to keep baby full and to maintain supply. Often a sucky baby will indicate a growth spurt or your body's way of boosting supply. After bottlefeeding my first son (due to complications after birth) and then breastfeeding my next three, I would be happy to never have to sterilise or heat up another bottle in my life. This, of course, is my opinion, but if you've come this far I think it's worth a few more weeks. Ultimately it comes down to having a happy Mum and a happy baby. If Mum isn't happy, then Baby isn't happy! Hopefully someone will have experience of doing both and give you some advice. All the very best in whatever you decide.
