Stefka, I have never rocked a baby to sleep. I now have a 3yo who was always fed to sleep. As she got older, she needed it less and less and now her dad can put her to sleep w/out milk, but i still give her a quick feed in bed, unlatch her and she rolls over and goes off on her own.
just before her 3rd birthday, she demanded to sleep in her own room and refuses to come into our bed at night/or in the morning when i would like a lie in.
even without your eating issues, i think you would be really tired now anyway if you are getting up during the night ot feed, say once or twice and even if you are awake for only say, 10 mins.
the thing with co-sleeping which makes this not happen, even if you are feeding several times a night, is that you and your baby enter light and deep sleep cycles at the same time so he won't be waking you up out of one of your deep sleep cycles to ask for food. Plus, i never seemed to be awake for more than half a minute to feed dd.
I worked full time since dd was 4 mo old and she did not wean onto solids properly till well over 10 months so I know about frequent night feeds. In fact, i was very run down around when seh was 8 months old and my gp suggested weaning her from the breast so i could get more sleep. I didn't follow his advice, I started to cosleep full time instead and I haven't looked back since.
It was a good thing i didn't wean her either as it turned out she is allergic to egg and cow's milk protein, which we didn't know back then.
