Mirena and t zone

I had mirena put in in Oct 08. My symptoms are: dizziness, sweating, nausea, (these symptoms can be mild and brief (seconds); or last a few minutes. I had severe dizziness in May and June of 2009. I also get acne on my shoulders, neck, face, and my T zone is very oily (especially my forehead). I am using good acne products to try to combat this problem, but I continue to have a problem. Some of my acne is like welts and I even have this going on on my scalp. I wrecked my car in December 2008. At that time I was very foggy headed. I blamed the foggy headedness on being stressed and overworked. I am 40 years old. My children are 10 and 13, therefore I know my symptoms are not post pregnancy. Today, I questioned if I wasn't going through early menopause. My doctor said this mirena would be wonderful and that after six months I would not have a period anymore. I have a period every two weeks. My periods are very light, but I still have them every two weeks, and they last for two weeks. I have been wondering if my body will adjust, and if I will eventually get to this heavenly place of now periods and bliss?

Oh I forgot to mention acne in the t-zone, pain in my knees, short term memory issues, and numbness in my right leg often. I don't know why I have been putting up with this thing for so long. Some people say anything is better than being pregnant but that couldn't be further from the truth.

I had my Mirena inserted in April 08 with a lot of effort! First the gyno could not insert the mirena......he tired a couple times and it just would not insert. I was in extreme pain. So a week later i was booked in to be put to sleep so it could be inserted....successfully. Obviously i could not feel anything this time. I was told that my cervix was closed and that is why it was a lot of trouble. Since the insertion i have had acne on the T Zone (i have never had acne before), and i have gained 4 kg (i work out 4 times a week and have always weighed 56 kg). I have not had a period which is great, and it has not affected my sex drive. But the acne and the weight gain do greatly concern me. I am thinking of having it taken out. Hmmm....what to do??
