I've had nausea for 2-3 months when I wake up, at noon, and in the evening, especially after eating, but I don't necessarily eat too much.

If you have been experiencing nausea for several months without any identified cause, it would be best to consult with your doctor to determine the underlying issue. While temporary relief can be found in products like Gravol or ginger, it's important to address the root cause of the problem. Uncontrolled anxiety can also lead to loss of appetite in some individuals, so seeking treatment for anxiety may also be necessary.
