Metronidazole and metallic taste

I've taken Metronidazole three times/day for two weeks for a foot infection. The metallic taste and nausea appeared after 7 days. Now it's horrible... every single meal that I've had since I've been taking the pills now gives me nausea, so I can't eat. Today I had a cup of coffee and it has been the most horrible experience (nausea, vomit, headache). I've felt really tired, I can't work, because of the nausea and fatigue. I'm done... will not continue taking my pills any more! DO NOT DRINK COFFEE IF YOU'RE ON METRONIDAZOLE!

Metallic taste after using the TOPICAL form! I stopped using it five days ago but still have the taste and sometimes my tongue burns.

I have not taken any medication in many years as I am generally healthy. After taken these large nasty pills, I feel very dizzy, spacey and sleepy. I have been prescribed 500 mg. for 7 days and since day one I've felt this way. This is day 4 and I feel very sleepy. The taste is HORRIBLE and everything I've eaten since than has a metallic taste.
