lee, I totally understand. We must all do what we must. That said, formula may make things easier... or it may not. If you're baby is high maintenance, then he will be so regardless of how you feed him (and fiona's advice re reflux is good). When babies are little, it's all about feeding. And when things are tough and we're breastfeeding, that's often the first 'problem' we identify and try to change. But it isn't always the answer.
Try the meds first. And maybe try a different one too if that doesn't seem to do the trick.

It's great your DH is helping out at home. Try to get some baby-free time too though! Even if you do have to do the dishes (though getting out somewhere for 30 minutes by yourself would probably be even nicer)

For what it's worth, my first was also like this. He had silent reflux but luckily he grew out of it by around 12 weeks.
I know you probably don't feel it, but you are doing a good job in very trying circumstances.
