hi i recently had an contraceptive implat put in around 6 months ago since then i have become more irritable, moody,tired, stressed and terfull wich is so unlike me i am normally very level headed and can deal with my emotions, also since the i had the implant when i go on a night out and drink alot i have become a little agressive which is also unlike me i feel like my hormones are all over the place .could this be why i have become more moody when drunk as before i was a happy drunk?? thankyou
