You don't need to drink if your foods contain lots of moisture. What you excrete (your urine) is an excellent guide as to whether you're getting enough water. Medium dark or dark urine suggest you would need to consume more water -- you might like it better if it's flavoured and/or chilled. Fresh urine should not have an odour. Do you smoke, or live / work amongst smokers?
You might try green tea and acquire a liking for it. It's a very healthy choice for several reasons, but does contain caffeine (so is not well suited at times if anxiety were a major concern).
I think the bigger concern, besides the idle curiosity about why you don't experience feeling thirsty, is that your period stopped for a whole year around the time you were having severe headaches.
Did the doctors just shrug and give up, and you still aren't menstruating?
the doctors basically gave up. We did a LOT of tests and scans and everything was normal. If I had a tumor or something they would have found it. And yes I have not had my period since about a year ago when the headaches started (even though I no longer have the headaches).
Headaches can be a symptom of changing hormone levels. A lot of women get headaches during certain parts of their cycle, and many women get them in the early stages of pregnancy.
So the headaches and cessation of menstruation could be related.
Do you exercise a LOT? At 5'2" and 110 pounds, you're not too thin to be having periods - your weight sounds perfect.
But if you're exercising a lot, that can cause cessation of menstruation.
The reason it's important, Lolli, to find out why you've stopped menstruating is lack of periods means your body is in distress for some reason. Fertility shuts down if your body isn't functioning well - it's saying, we're barely holding on here, can't take on a pregnancy.
I'm very surprised your doctors just shrugged and went on. You probably should seek help elsewhere.
