My frog woke me up at least six times a night during the last half of TX and would be banished only with the fizz of seltzer water. I used the cans as the big bottles lost the fizz too fast. Our recycling bin overflowed those months but nothing else really cut the mucous or soothed my throat like seltzer. Everyone is different though so it may not work for you guys, but my doctors thought it was just fine so long as it worked. Hang in there.
