I am not aware of any vitamins or minerals taken as daily supplements that could cause a "false smell of alcohol breath." Nor am I familiar with Diflucan causing it directly or interacting with other drugs to cause it. Rather than Diflucan for yeast and other fungal problems you may wish to try a natural product called Candex produced by PureEssence Labs, 888-254-8000.
It is possible, however, that you are perceiving this smell with ketosis. Ketosis occurs when your body has shifted from burning glucose for energy to burning ketones. This occurs naturally after not eating overnight and after exercise. Excessive ketones are eliminated in your urine and in air that you breathe out.
Ketones are NOT bad unless you are a Type I diabetic. In fact, your heart and brain run 25% more efficiently on ketones than on blood sugar.
You can increase the elimination of ketones and ketone-breath by increasing the amount of water you drink. You can safely drink up to one half your weight in ounces of water every day. For a 160 pound person that would be 80 ounces or 10 glasses of water daily. That is an awful lot of water. It represents the upper safety limit for intake. You may never consume that much every day, but if you are not drinking even close to that amount of water every day, you definitely need to drink more. Adding fresh lemon or lime juice to water makes it tastier and easier to drink more.
One other consideration would be that some people produce excessive amounts of alcohol in their gastrointestinal tract. This is rather rare, but if you are not experiencing ketosis, this may be something to explore. You can have your urine tested for ketones. You can also probably purchase ketone test strips via the Internet. Just search for Ketosis and follow links until you find a source of test strips. If your urine is not showing excess ketones while you are experiencing "alcohol breath," see a physician that may be able to test you for excess production of alcohol in your system.
