I don't know how anyone can do this without feeling intensely ill. I drank a gallon in about 40 minutes once, and it was readily apparent that nothing about it could be healthy, pleasant, or in almost any way a good idea.
Like water it’s fine until you’re swallowing pill after pill.
Also, tendon injury/tendonitis seems linked to ibuprofen use. It may delay other kinds of healing (bone fractures, etc)
10 litres was an exaggeration of course. I think like 6 or something in a couple of hours is dangerous from the doctors I worked with?
This is from a group of fitness obsessed people doing very arduous exercise.
