The pills seem to be working pretty good so far. I did have to take 4 pills at once, in which I experienced a slight headache and dizziness. The only negative thing about taking the pills is the after taste.

I took my last pill of this medication yesterday, and I am so thankful to be off of this medicine. I had been taking 2 pills per day for 7 days. The taste was horrible, as so many other people have noted. For hours after taking the pill, I had a bitter taste in my mouth, and everything I ate tasted bitter too. After 2 or 3 days on the medication, I began having panic attacks. I hadn't had a panic attack for 2 years before this. At first I wondered if I was having a relapse, but after realizing that other people taking Flagyl have depression or other mood problems while on the drug, I thought differently. I hope that since I am done taking Flagyl my anxiety will go away. Finally, I also felt nauseous and lost my appetite while on the drug.
