When I was bombed at the Montreal Jazz Festival here is exactly what I mixed with flagyl drinking from about 2-5 p.m., with 500 mg flagyl dosages taken at 9 a.m. and 9 p.m. the same day:
1 Mango Sunrise (rum, mango liquer, mango juice and other ingredients I forgot; advertised by the bartender as "sweet and girlie", but tasted strong and not so sweet to me)
3 Bellinis (sweet "girlie" type drink with rum, chambord, peach schnapps, sparkling white wine mixed with ice and cream; delicious!)
2 shots Jameson Irish Whiskey, purchased by a random guy from Toronto who wanted to "man me up" after watching me drink the Bellinis
1 "Jagerbomb" (large shotglass of Jagermeister submerged in a glass of Red Bull), also purchased by the guy from Toronto who said he wanted to "man me up"
I am not in the habit of refusing free drinks because I am taking flagyl. Sorry.
Anyway, for me, no side effects.
