The most important and common cause of inability to sleep is stress so I will not rule that out completely. At the same time there can be other reasons also like GERD (gastroesophageal reflux disease) which can cause nausea, bloating, headache and knot in your throat.
I would advise you to eat your dinner at least two hrs before your bedtime, avoid oily food. You can also try going for a post dinner walk it will reduce your stress as well. You can also take a mild OTC antacid and see if they help. If these measures do not help please schedule an appointment with a physician and undergo a complete physical examination.
