Re: New here - please help. Felt ill every night for months....
I think you should talk to your GP about what would be safe to help you sleep and be compatible with breastfeeding. I believe you can take zofran when you're nursing, it's a prescription nausea med. You can take it when pregnant and it often prescribed for morning sickness. You may also be able to take unisom to help you sleep; again it's often recommended to take if you have morning sickness.
In general, not eating enough in the evening definitely can upset my stomach at night. I get over hungry and acidy. I take a zantac at night as per my gastro, and she told me it was safe to take pregnant (since my husband and I are hoping to have a baby in the not too distant future), so I imagine it's also safe breastfeeding. Something like that might help you at night too. But of course, check with your doctor!!
And this may be a totally random suggestion -- can you sleep somewhere other than your bed? Sometimes when I'm not feeling well I feel really panicky I feel trapped in my bedroom. I go down and lay on the couch and watch TV and can fall asleep easily there. You could try making yourself a nice cup of camomile tea with honey (good for digestion and sleep!), get cozy on the couch with a blanket and a pillow, put on a favorite movie or TV show and see if you sleep easier someplace outside of your bed.
