Metronidazole and bacterial infection

One week ago tomorrow, I was diagnosed with BOTH a yeast infection (my first) and a bacterial infection. The doctor gave me the generic forms of Diflucan and Flagyl. I think this medication is interfering with my sleeping. I've been taking 500 mg 2x/day for a vaginal infection and I can't sleep at night. I take the pill between 7-9am and 7-9pm and since I've started, the only night I was able to get any sleep was the night I took some Benadryl. To boot, I'm STILL having problems with vaginal itching and I don't think the Metronidazole has helped my infection at all. ARGH!!!

I took this medication for 7 days 2 times a day for bacterial vaginosis. I thought I was pregnant!!! I am always regular each month and on this medication I got my period 3 days early! It was thought to be implantation bleeding because it was very light etc. All except it lasted 8 days my period only last 4 days. I believe this medication messed my cycle up for the month. I just got the results from a blood test I am not pregnant!!!? It's got to be from the antibiotic. Has this ever happened to any one????
