Has anyone ever used these colic drops?

my son is 7 1/2 weeks old and has real bad colic and gas, i bought him these colic tablets by hyland's and they say that it could help him sleep but we have gave them to him twice now and he has fell asleep with in 15-20 min. not complaning (he seems alright and able to rest which we all need) but just wondering if anyone else has used them and what happened and did they help you'r baby?
