Many ways to help, but don’t trust any drug even if your doctor assures you that the drug is safe!​
You got mails from me in the past about ginger, B6 etc
Simple to try is also lemon etheric oil [essential oil].
Not all etheric oils are pure !
Put a 2 drops on a cottonwood and inhale deeply a few times whenever necessary.
Some times one or two treatments  with acupuncture can help a lot as well.
