When DS was a baby and adeks switched the formula to create Aquadeks drops, I'd gag every time I'd put it in the oral syringe. Smelled like someone had a sinus infection. Nasty. Fortunately he didn't mind or notice. Switched to Source CF Chewables and then to the softgels. A week ago I ran out of SourceCF and switched to Aquadeks softgels. Every morning this week I've noticed DS's breath smells different -- like he has a sinus infection. But his nose is clear, no cough, just had cultures run and nothing growing.... Yesterday got his afternoon meds ready and caught a whiff from the bottle of vitamins. Yep, nasty aquadeks smell. Least I know what it is now. But, bleah!
