nausea/vomiting
"Promethazine quickly relieved my upset stomach/nausea due to other medicines (I think, who knows, maybe it was a bad meal or lack of nutrients in my body) I love to have this medication in my cupboard if ever my stomach acts up, or if I have an allergic reaction to something. A full dose makes me very relaxed and I generally take a nap. A half a dose just gets rid of the ailment and I can still function in my day. I love this little "cure"!"
