<s>[INST] Lately, I have been getting very sick the next day after only a few drinks 2-4 over a span of 3-4 hours. Sick to the point where my head pounds, i vomit frequently, nothing stays down (water, bread) and only start to feel better in the evening (6-7pm) I have plenty of food in stomach though. Also, had half a beer tonight and felt sick instantly, now my liver is aching. [/INST] Hello,It looks like you had indigestion or food allergy. You can take anti emetics to stop vomiting, one SOS when needed. It should stop, if vomiting does not stop you will have to take injections. After you have stopped throwing out you should keep yourself well hydrated. Take soups & ORS.You are suggested to visit ER, get clinically assessed by a GP. Get Urinalysis, blood tests (liver function tests) and USG (liver and gall bladder) done to detect any liver enlargement or any other developing pathology. Take boiled food and food that is easily digestible. Avoid taking raw food or fruits. Cut on alcohol and addictions if any. You can take antacids and PPI's for relief.Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K, General & Family Physician </s>
