I've been sick for a few years now with GI problems, but they have been caused by medication I was taking for (misdiagnosed) seizures. Don't get me started on that novel, its a nightmare, but the short of it is the health problems I have at the moment start 5 years ago and are either something hormonal or neurological. I have regular night sweats, every night, and they are completely drenching maybe 2-3 times a week, I can get to sleep fine but I wake up about 2 hours later and then I sleep in bouts of 30 mins - 1hr, extremely fatigued, but the stuff that has me and my Drs suspecting premature menopause, apart from the night sweats, is that my period, which has been really heavy in the past, has gotten light to the point it has almost stopped and its been getting lighter for the last 8 months, I'm moody as hell, usually easily irritated, and I'm having lots of mood swings and periods of heightened anxiety that I can't attribute to anything. It seems different to my normal depression and anxiety symptoms, normally when I'm getting bad I don't have days where I feel fine and normal, I just spiral down and there is little fluctuation, but what I'm getting at the moment is small spells, lasting no more than a day at a time, the I go back to normal for a few days, but when they do happen I seem to swing to the extreme of either irritability, depression or anxiety.
Since my original post I've seen an endocrinologist but shes pretty stumped at what it could be too. Its pretty frustrating.
