Dr called back several times checking on him gave several options. First try sipping hot fluids broth tea etc to see if the foaming saliva clears our of stomach and he still has some discomfort but keeping half down. He did this several times in 30 minute intervals and calls with dr first couple no success everything came up. This last time a little better. Dr worried about dehydration. Said he should be better after the saliva clears out if not back to hospital for an Iv. Finally resting was able to keep meds down. Thanks everyone for the tips. Dr said to try a straw also
