constant hot flashes?? is this normal?

[♥ms.pacman♥]

i am having what i think is hot flashes pretty much constantly (90-95% of the time i am awake). I ALWAYS feel so hot to the point where i cannot concentrate on ANYTHING and i feel uncomfortable all.the.time., not to mention it's embarrassing to be sweating all the time. It's beyond frustrating especially now that it is summer. I heard this is a side-effect of breastfeeding, but this honestly is waaaay too much..it is starting to really interfere with quality of life. DD (who is EBF) is 3.5 months already, i thought this was supposed to be gone now? I had this issue after DS, but not nearly as bad...not sure what is so different this time.

Anyway, I think something is wrong because when we're out somewhere i'm always asking DH, is it me or is it a billion degrees in here? ANd DH (who is the guy who can walk in 50 degree weather in a Tshirt and shorts), says, no, it's actually a bit cold! :S

any BTDT or ideas what this could be? should i ask a doctor about this? i am so sick of having to set the thermostat to 73 degrees and turning all the ceiling fans on in the house and still feeling miserable!! it feels worse when i'm nursing, but i still feel it at other times. i almost NEVER ever ever feel cold anymore, and i am normally a person who is somewhat cold all the time and would set the thermostat to 77/78 in the summer.
