I have had mirena inserted just a few days ago. As a result I have much more energy then for a long time ( a lot of energy ). I have been suffering from sugishness and aches and pains, tiredness etc for a long time. How come do I seem to have an opposite reaction to most people? Is this normal? I feel great, no no complaints, but it seems a bit odd as most people seem to feel they have less energy? Has anyone else felt this way?
