Hi there,
I welcome you to healthcaremagic.
You should definitely go see a doctor ,if you do not get better within 48 hours and before you become dehydrated and have other complications.The lobster was definitely contaminated by a bacteria,so watch yourself for 48 hours. Food
poisoning often improves without treatment.To help keep yourself more comfortable and prevent
dehydration while you recover, try the following:
Let your stomach settle. Stop eating and drinking for a few hours.
Avoid certain foods and substances until you're feeling better. These include dairy products, caffeine, alcohol,
nicotine, and fatty or highly seasoned foods.
Ease back into eating. Gradually begin to eat bland, low-fat, easy-to-digest foods, such as soda crackers, toast, gelatin, bananas and rice. Stop eating if your
nausea returns.
One your vomitting stops start taking Oral rehydrating fluids.
Hope i helped.Take care
