I've struggled with a lot of nausea and have found a few things helpful (other than the usual ginger/soda crackers/etc.):
One thing that may help is a homeopathic remedy called Bryonia Alba (NOT the herb itself) that helps to treat nausea from sitting up. I keep this remedy next to my bed so I can just grab it and take some then wait about
5-10 minutes and try to sit up. It has been very helpful for me. I get my homeopathic remedies at a local health food store but can also be ordered online (I use abchomeopathy.com ~ I have no financial connection with this website). I also use homeopathic Ipecac. (NOT the syrup itself) to help with nausea/vomiting.
Another thought is motion sickness wrist bands - these are wrist bands that stimulate an acupuncture point on the wrist to reduce nausea. I got a set at a local drug store (no prescript
ion needed - they're over-the-counter).
And you might ask your doctor about
stomach motility medications. Reglan and Domperidone both promote normal stomach emptying and also reduce nausea. Domperidone must be obtained from Canada or a compounding pharmacy, but it has fewer side-effects than Reglan.
