Stan's Guide advises against this due to increased risk of vomiting ruining the attempt. A little hard candy in the mouth for a few seconds and then spit out seems to work. You can do whatever you like, though, it might work. Someone here drank a lot of alcohol with their attempt, which has the same issue, and the first sn attempt failed due to vomiting but the second attempt seemed to work. Truthfully if yuou don't use too much maybe this will help to keep it down due to masking the taste- no one knows for sure- but it might actually help.
