When the scale starts moving, I feel ill...hormones?

I am on track, losing just fine but I am also a staller. I stall a week, loss a large amount..stall two weeks...loss 10lbs and on and on. I know this can be a normal pattern so when im not losing I just stay on track and go with the flow. Thing is, after a stall, I know when its over because I start feeling bad for a couple of day in. I am exhausted, my heart is racing and I am dizzy. Blood pressure is normal, as is blood sugar. I get plenty of protein, water and my vitamins. Like right now, Im coming off a 2 week stall. But starting last night, my heart rate is up, anxiety, dizzy when i walk around and my TOM started. Also my face is red and hot. Im wondering if its hormones. Has anyone had this kind of thing happen? On a bonus note, I'm 5 lbs away from 100lbs lost since december! Happy dance!

I don't get like that but wanted to say Congratulations on your weight loss, that's awesome!
