Nope. Been there, done that. Antibiotics indiscriminantly kill all bacteria (including the good bugs that keep the bad ones in check). They may reduce the total bacteria count, but unless one can quickly repopulate the gut with good flora after an antibiotic treatment, drugs usually make the dysbiosis worse. That's what has happened in my case. I'm following a more natural (and ultimately effective I believe) approach of introducing probiotics through cultured dairy products (from goats, because goats milk is easier for humans to digest), cultured veggies (i.e. homemade saeurkraut, etc) and other fermented foods. I believe that foods and food-based probiotic products are far more effective in reaching the large intestine than 95% of commercial supplements.
