Hi Loretta,
sorry, I didn't see your original post or I would've replied - it can get very busy on here and posts do sometimes get bumped down to the bottom without anyone noticing. It's happened to me, there's a lot of us on here needing help so don't take it personally. I've had a huge amount of support at times when I've been desperate and there was absolutely no-one else around who uderstood.
On the subject of the Mirena, you don't say whether you've tried other regimes first. I certainly wouldn't try it as a first option - it's possible you might hit lucky and find it's ideal for you, but I and many others on here find continuous progesterone intolerable, even in the supposedly small amounts contained in a Mirena, and even if your doctor tries to claim otherwise it does still reach the brain and so can have mood-altering effects. I had to have mine taken out after 3 days as it was making me so panicky, but I do seem to have a problem with progesterone in general - might not be the case for you. Have you tried other progestins first?
