Heres a good idea, though it only works once and depends from npc to npc
If you forget the information on the quest, just discard it and get a new quest from the npc
if the npc can give more than 1 quest, it will probably give you the one after that
Once you finish any other quests it gives you, you can restart the discarded quest and see the information again, but remember to write it down the second time
I had this problem with the quest that gets you the energy glyph
But now the npc servers are down and i cant complete it
