They purposely make things last for a certain amount of time so you have to buy more, I have the same issue with my allergy meds. Just overall , I feel with most things. Similar to planned planned obsolescence
Interesting. I have a metabolism that doesn't hold medication well. I.e. it tends to wear off on me faster than other people. I can lose or gain weight almost as fast. So I guess it would be interesting to see if there are guidelines for 24 hour claims.
If definitely doesn't help when you have a super fast metabolism : ( They have the technology and the means to make things last longer in your system but for profit they make it run out at a certain time.
An example is time release narcotic such as oxycontin they can make it last for 24 hour period but of course this costs waaaay more. But true point about metabolism some peoples bodies eat through meds far faster others and naturally will need more of a substance than others.
