Just as an anecdote, I have mild arthritis in my hands and I take Ibuprofen (Advil) several times a week and it has not been a problem for me. Hope you are feeling better soon.
Actually, Advil does cause alittle water retention in some folks, but TOM causes more generally. If you take it regularly, you won't see the spike in weight because you just always carry it, like weight from carbs. It goes away a couple days later just like TOM weight.
Yeah im freakin gout too!!! O_o i began "shark week" haha & i couldn't handle the pain so i took one at least...so i dont think we will gain, if anything just from the actual TOM... -_- itll be gone soon though!
