Dear padgolThanks for the question. Typically, it's best to avoid consuming alcoholic beverages for at least 48 hours after surgery. Even if you do consume alcohol, be sure to go easy. I wish you all the best.
It can take 6 to 12 months after surgery to see results. Some may see hairs growing 3 months after the surgery. If you are concerned it is best to contact your doctor.
5000 grafts seem like an extreme amount of harvesting as it shows on the photos you provide. Based on Dr. Rassman's article it would seem it is over harvested.
