Augmentin xr symptoms and conditions

I accidentally(thank God) stumbled to this site after typing in a search for : viral infection that causes dizziness,racing heart,lump in throat. Up popped this!!! I was horrified but at the same time relieved. I am 35 yrs old and for the past 2 weeks I have been suffering from panic attacks,dizziness,uncontrollable hunger,constant thirst,tingling in my lower arms and hands.
I've been on Yasmin for a year now and am just now noticing these potent symptoms. I was in a restaurant in a business meeting 2 weeks ago. I suddenly felt hot,sweaty and extremely dizzy. Scared me to death!!
I've since been to my doctor 2 x's this past week. She's prescribed Omnicef,Zithromax,Augmentin XR under the assumption I had a sinus infection or ear infection causing these symptoms.
I took my last pill of Yasmin 6 days ago for my new cycle,and coincidently called my OB/GYN and complained about how expensive Yasmin is. She switched me to Estrostep. Is Estrostep better,the same or worse than Yasmin?? I still feel like a bus hit me,head is light and dizzy,nervous,panic attacks have spread out but not left completely,and hunger has slowed down. Am I getting better? Do I still need to go back to the doctor? Can I be fixed? Do I need a supplement? I need to relax so I can mother my 2 children and function in my daily life. any suggestions?
I thank God I accidentally found this site. Although I don't think it WAS an accident....HE answers prayers in the most awesome ways.
