I woke up this morning feeling ok but later in the morning I began to feel lethargic and nauseous. The lethargy is what scares me the most, I get nauseous all the time but this particular feeling of lethargy is specific to norovirus for me, I ONLY feel that way when I have it and I haven't felt it in about 10 years, since the last time I got sick. I have this test I do that's always determines whether im sick or not, because it's the main common denominator. I do something physical, even something as simple as walking, and if I'm sick, I get bad cramps. Today that happened, along with nausea, diarrhea, and lethargy. I took a xanax so I can relax but I don't know what else to do. Would taking a suppository prevent vomiting?
