Lemon's Health Wonders: From Detox to Fighting Disease

Fresh Lemon juice vs ACV... An alternative therapist once advised me to drink hot water with lemon first thing in the morning to flush out my system and I know that you guys advocate for ACV also first thing in the morning and on an empty stomach. What I want to know is which one is better? I have been drinking the lemon with water and it was really working well for some time in terms of my system but now I feel like its not although ther are other benefits such no more cold or coughs. But is lemon juice good in the long term. Ted is always referring to the body's alkalinity and acidicty and how that affects our immune system so I wanted to know if lemon juice everyday wont do more damage to my body in the long run. Thanks
