  1. "...which tastes much better anyway." I love this guy.
  2. it's only narcotics that this happens with that you would notice
  3. M
  4. A question arises, why do we think, that medication heals our body, when our body itself does all it can to prevent them from getting into the system? Maybe an epsode on drugs, their composition and the mechanics of their influence on human organism would clear this out a bit.
  5. so if you can a Xanax with grapefruit juice you'll feel it more even if u don't have any more medication problems lbs
  6. What's that faint squeaky wheel sound I hear throughout all your videos? Occasionally I hear higher pitched beeps like it might be an actual sciency soundtrack, but my old ears can't pick it up completely.
  7. When you are telling your dad about this because you know he has high blood pressure and you find out it was actually him that discovered it XD
  8. Grapefruit cures high blood pressure. Thats why they say dont take it with hbp pills. God knew what He was doing when He gave us this fruit. doctors will never tell you that because it would put pharmaceutical companies out of business. so they just tell you don't eat grapefruit while taking his medication because of other reasons but the real reason is because they already know that grapefruit cures high blood pressure so if you take grapefruit along with the high blood pressure pills you're doubling the work on your high blood pressure which would drop it to an unsafe level. In their warning telling you to not eat grapefruit while taking this pill they were actually telling you that grapefruit has the same effect as taking this pill but most people are not able to catch this.
  9. I love me some Squirt Soda, the best grapefruit soda ever
  10. Hank, don't you dare talk shit about my juicefu
  11. That means the xanax will be more effective if I drink the grapefruit
  12. Now my fridge stay stocked with dirty GF juice 😄😄
  13. "The normal one" The popular one.
  14. Here in NZ we have this warning on contraceptive pill packets but I've not seen it on any other medication packets yet.
  15. H2O!
  16. wait will i be more fucked up or nah?
  17. Why are there grapefruits around my anus
  18. Currently eating grapefruit
  19. Is Hank secretly supported by the anti-grapefruit confederation?
  20. I prefer the taste of grapefruit juice over the taste of orange juice.
