Can I Consume Alcohol While On Dronis?

Hi, I have been taking Dronis 30 for 21 days now but the side effects have been crazy- too much nausea and headache. I’m an active smoker howeverr recentlu stopped because of dronis. Now I’m travelling abroad for 10 days and I’m wondering if I can consume alcohol while taking dronis? If not, can i stop the treatment for this month and resume in the next cycle?
