acne
"1) Cleared my skin up within 4 months. Still occasional problem spots around the time of my period but it's a joke compared to what I used to have to put up with.

2) POTENTIALLY IMPORTANT: When I got to the last week of hormonal pills (the super-strength hormone loaded ones before the week of placebos) for the first 5ish months on the pill I found that I would be prone to existential emotional breakdowns or feel more anxious/depressed than usual that week. I didn't notice the correlation for an embarrassing amount of time. I was very relieved when I did figure it out and I wish I had figured it out sooner. Now that I've been on it for a year this problem has almost disappeared. Just something to be aware of for the first few months!"
