Hi there, thanks for asking. It could be a sign that you have breathing problem during your sleep. If you snore, you should know that sleep apnea
is a disease that you should be checked for. The issue that you had this problem after using alcohol or drug is that airway problem during night is aggravated by drinking or using substances. It is good to know that you may have it, and fortunately it is not present in all the days at this time. Best wishes.
