OMG! This sounds just like me. I am on the depo shot (my 3rd injection as of feb 2013) and i was told from my hot flashes (my ears or one ear gets really hot and so does my face) that the depo shot send me into an induced menopause. I have hot flashes and nausea, bloating, not able to sleep (i keep waking up), bloated, no period since i had this shot, and constipation!!!
I am sure this will not help because your post is very old, but i wanted to let other women understand about what can happen on this shot!!
Since i been on this shot my hormones have been all out of whack!! It is ridiculous!
