Hang on ladies be careful here its not anything or anything dissolvable, i found out much to my horror as i thought the same, the dissolvable stuff contains Citric Acid and its not mentioned on the box either you need to go online and look at the website.
You can only take tablets like paracetamol, don risk anything else unless you looked at the ingredients online and not just the box.
When i was ill i took solpadine, said nothing on the box, then looked on line and it had citric acid. I almost fainted, luckily i was not knocked out of ketosis.
