Sweet food symptoms and conditions

This is my 2nd pack of Alesse, and I think i'm going to stop after i am done with this pack. I am experiencing breakthrough bleeding all the time, im irritable, i get lightheaded all the time, and i cant keep away from sweets! With the breakthrough bleeding, I feel like i'm getting my period and i get the cramps and back pain along with it. I know it's due to this pill because I have 2 kids and I am very into healthy eating and working out and i have a lot of will power when it comes to sweet food and chocolate. Also, by 5pm or 6pm, I am soooo fatigued that I can't even drive, I just want to sleep! People say to be patient and give it a few months, i totally disagree, I am not going to mess up my body. i think I am just going to stop birth control overall and try a different method of birth control.
