No wonder you hadn't posted in so long! My boyfriend says that drinking lots of water can help with headaches if you don't normally drink just plan water. He actually had problems with headaches and then want to drinking mostly water and doesn't get them as much anymore.
That's the reason I haven't. I've been trying to drink more...I dunno if it's just that, I think my sinuses are acting up too (or my head just hates me)
