i figured i would add to the conversation.
I am OPs boyfriend. My first experience with L was at bonnaroo a couple years back, and have since become a self-called "experienced" tripper. I've always taken great measures to ensure positive experiences, making sure that logistically everything we may need is accessible, not tripping alone, testing paper in small quantities initially to measure strength of L, etc. etc. I enjoy tripping and generally do not have bad experiences.
OP, healthwise, is fine. (side note: its funny calling my girlfriend OP haha) I do not think that her "block" is triggered by medication. Also, we have tried numerous different batches of L. We've been bunked maybe twice at festivals but it was definitely bunk becuase no one who ate off the strip tripped. We do not get low-quality L often, which is fortunate becuase living in the Southeast can make it difficult to get any sort of quality L. We've had legit fluff, champagne crystal, lavender crystal, etc pretty regularly and they are strong. I have a generally low tolerance for L; I take 1 hit if Im just looking for a chill trip/seeing a band or something, and take 2 if I'm trying to get space cadet status, or if one of my top bands is playing, etc. I've never needed to take 3+ hits, and I probably won't ever. Our setting has never been in an uncomfortable place- we've tripped at numerous festivals, multiple shows and venues, at my house, at her apartment, outdoors, etc. and there hasnt been much difference.
When tripping with OP, we are generally on the same level during the come-up, but once the peak begins she just doesnt quite get there. After a couple hours (as I'm coming out of peak), we're generally back on the same level, but I feel like what she is experiencing is only really the typical "side effects" of an L trip- dilated pupils, slight lingering visuals, not much of a body high, cant sleep, etc.
I've done my research on L and know my stuff pretty well. It is my theory that OP is just mentally "harder to break" than some people. What is causing that? Im not sure- we're trying to figure it out. But we do know that if I take 1 hit at a show and she takes 2, we're basically on the same level. So we're thinking that perhaps she just has a higher mental tolerance than average people.
Thank you bluelight for helping us with ideas on how to overcome this. OP is a wonderful girl who I am blessed to be with and love dearly, and I want her to "get there" with us and have that awesome first-time mindblowing experience, not just watch our friends and I trip balls and have to play babysitter.
