My husband is in 25 week therapy with Epclusa. He asked me to check with you, how much water he needs to drink when he finishes therapy? He is tired of drinking plenty of water, and think that he could be back on usual amount of liquid when therapy ended. He drinks about 5 glasses of water during the day, also he is vegan and there is more liquid in that kind of food.He is also worried about constant pain in liver and asks if someone has equal troubles? Thank you!
