Using Crina NCR, need advice. Tablet?

I had a ulcer on my appendix and got it removed laparoscopically in December and till then for about 4 months I had severe bloating and pain in the abdomen. I am better now, but I am traveling and needed to postpone my period and I have used dronis 20 for over 3-4 years, on and off for 3 months at a stretch and not used for 4-5 months, I have PCOD abut as of now no cysts acc to my ultra sound in November. My Guanches advised I use CRINA NCR for 9 days and no need of dronis 20 anymore. So my question is as I have extremely sensitive skin and pcod problem is it safe to use CRINA NCR and can I consume alcohol when I use this tablet? Please guide me. I want to be careful as my stomach is extremely sensitive right now and I still have pains and bloating if I eat something wrong also. So..
