I've had a similar experience, but I wasn't on drugs...I was just seriously in love 3 days after meeting the girl...but i don't think it' much different cos you're brain gives off chemicals when you fancy a person and you're not in a normal state of thinking anyways...

To make a long story short it didn't work out between us, but that soesn't mean to say it'll be the same with you guys...all i can say is to sit down and indentify the difference between being "in love" and actually loving someone cos there's a big difference and i would first try and establish a relationship with her before you think of moving...but that's just my opinion...
