Well, my thirst levels are about normal for me - I don't feel any more thirsty than I usually do, but then I tend to drink a lot of water anyway, provided I have it handy.
I'll probably mention it to the GP when I rock up for an appointment - I need to make one some time this month anyway, since I'm going to need a new script for the Zoloft 50s... yay. Hate visiting the doctor - always feels like I'm wasting their time unless I'm actually in the throes of something nasty.
