I started taking Aviane last night in hopes that it will help my peri symptoms. I woke up at 1:30 in the morning with heart palps, burning hands and feet, and very anxious, managed to calm myself down and fell back to sleep. This moring I am having hot flashes, foggy, slight headache and some anxiety. Has anyone else experienced this after starting the pill? If so how long before your side effects went away? By the way, therse are the symptoms that I have when my peri is at it's worst.
