I have low blood pressure (80/50) and my Dr. said to drink more? - what is low blood pressure more condition_symptoms

Water. Drinking water throughout the day only to go ice tea (no alcohol), but I smoke and I'm on pills, painkillers (oxycodone), due to a fracture. How do I get my blood pressure higher?
