Hi Bobby, the tea, honey & lemon will soothe your throat, as well as help break up mucus.
The acidophilus your friend suggested is an excellent idea AFTER you finish your run of anti-biotics. Even better would be a combination bifidus, thermophilus, acidophilus, and other LIVE cultures, easily found in live culture PLAIN yogurt (the sweetened kind will FEED undesirable bacteria).
The purpose of introducing these cultures AFTER anti-biotics is simple. As the anti-biotics work at killing the intended bacteria
http://www.healthboards.com/ubb/alien.gif i.e. in your throat, they ALSO kill off all the bacteria in your intestines. Partly, this is a real good thing, as it kills the nasties (like yeast
http://www.healthboards.com/ubb/t_down.gif) that are present in your (all of our) intestines. The live cultures you introduce after the anti-biotics restore the NECESSARY bacteria

you REQUIRE to appropriately process what you consume.
If you introduce with sugar-laden cultures (like ALL fruit/or sweetened yogurt), then the bad bacterias have a marvelous environment to grow

, and since it's so clean in there, over grow, and potentially squeeze out the good guys

As for the l-lysine, I'm not sure about the intention there. It is an amino acid and as such, works more synergistically if combined with other amino acids

Hope this helps (helped me, I OBVIOUSLY had fun here!
