Ok so my LSD arrived today and I'm planning to do it next month. I only took LSD once before, many years ago, in sugar cube form and then wandered around the countryside feeling blissed out and at one with everything, but it didn't feel overly strong, may have even been a placebo. I've only been meditating solidly for about 3 months and haven't done really any self enquiry. However I'm quite a well rounded individual and have been studying Buddhism for about 10 years and non-duality for about a year and a half. I have a solid grasp on my true nature as being awareness, although I haven't had any mystical experiences yet. I've watched all of Leo's videos, taken notes on all of them and do personal development throughout my day and nothing else. This is also includes shadow work. I also do a lot reading, have digested Ralston, Byron Katie, Tolle, some Om Swami. I understand 'being cognition,' the relative nature of reality and can reside in no-self when I wish by letting go of all concepts and ideologies, although not for long periods, 
One or two people on the forum have expressed concern for my welfare as it's my first time tripping and I haven't done much of the actual solid, spiritual practices, although I know all the theory (have theory coming out of my ears) and I feel I can do a good job of residing in being for the experience and getting some good insights. I've been advised to let go of all concepts, which I understand, but then again, if I want to ask questions, some concepts will be needed right? 
But the core of my question is, am I jumping in too deep here? The LSD is 150ug and 98% pure. The guy I bought it off recommended I take 115ug my first time but I'm inclined to go for the 150. It might also be worth mentioning that I'm a veteran weed smoker (although given up now) and I've had many intense experiences on that, which had started to induce panic attacks towards the end of my habit. Therefore I feel I can keep my head together during the trip. I've been told the trip will last 12 hours. I'll be renting out a hotel room to take it.  The way I see it is...I'll be fine as long as I have 'mystical cat' to guide me
