Should I Switch Back To Beyaz After Gaining Weight And Night Sweats While Taking Kelnor?

I am a 32 year old female. I quit taking birth control December 2013. It is now May 20, 2014 and in that time I have gone 120lbs to 140lbs (5 4). I was originally on Beyaz and then in April 2014was put on Kelnor due to the price increase on Beyaz. I know that Beyaz has a diuretic which can help with water weight. I feel like the Kelnor has done nothing but freak my body out more! My question is, if I go back to Beyaz (which is what worked great for my body with no weight gain) will my body go back to how it was before I discontinued the Beyaz brand pill?? The 20lbs I have put on in a matter of 5 months is crazy plus I am having night sweats and my face is broke out! None of this have I ever dealt with in my life! Bascially I just want my body back to where it was before I went cold turkey off the pill. Also, I have been on birth control for 14 years and have made no changes to my diet. Please advise, my body is freaking out!
