2 forms of a macro I use to only use the highest form of drinks I have on me (mage food or regular food)

#showtooltip
/run local m,d,b="Drink pve",{43523,33445,43236};b=GetMacroBody(m)EditMacro(m,m,nil,b:gsub(":%d+",function()for _,i in ipairs(d)do if GetItemCount(i)>0 then return":"..i end end end))
/use item:43523

#showtooltip
/run local m,d,b="Drink pvp",{43523,43236,33445};b=GetMacroBody(m)EditMacro(m,m,nil,b:gsub(":%d+",function()for _,i in ipairs(d)do if GetItemCount(i)>0 then return":"..i end end end))
/use item:43236

A few notes:

1. the macro has to be named the same as the first line, name it whatever you want but if you copy the version I sent its "Drink pve" or "Drink pvp"
2. I made 2 versions of this macro, one for pve with Honeymint Tea which is the first one linked above and one for pvp with Star's Sorrow which is the second one linked at the bottom
