Before you try to sound like you know something check the facts.Your trying to compare them to Angels Trumpet or Datura is about the most ignorant thing I have read on these boards.
Nullific knows more about drugs/organic chemistry than you will ever know so dont even try dissing him. It makes your tired and sleapy BECAUSE it is a delerient. He wasn't comparing it to Angels Trumpet or Datura, just stating that they are other substances that containt delerients.
jbuckets Reviewed by jbuckets on . Diphenhydramine Pseudophedrine and DXM My mom just went to the pharmacy and got dextromethorphan, Diphenhydramine, and pseudophedrine for my cough. I was wondering what a good first time dose of Diphenhydramine is. What is a pseudophedrine dose for first timers(not ephedrine)? And also is grapefruit juice effective with DXM like people say because I only have 400mg and I feel like a high 3rd plateu dose. Rating: 5
