Welcome to the Nexus!
Thanks for the long essay, its always a good way to get to know more about the new members 
Every LSD is man-made.. This doesn't mean its necessarily a bad thing, there are natural products which are harmful, and man made products which are relatively safe/beneficial. That being said, with LSD there is an added danger that it can be another substance sold as LSD. That's why we recommend people to buy reagents such as ehrlich (look up the subforum in my signature for more info), as well as looking under UV light (quickly because too much breaks down the LSD), because then you can see if its LSD or not.
Each one will have their own metabolism, psyche and lifestyle, so I cannot tell you whats best for you, you'll have to find for yourself. I can just say that from my own experience, while smoking daily certainly has its benefits/pleasures, over the time it takes it's toll, and it can affect concentration, memory, motivation. You said you tried staying some months without, which is good.. But did you try for example just keeping it for weekend use, or at least just using at night after all the tasks are done?
Also unrelated but related, how's your physical aspect doing, do you do regular exercise?
Please try turning off the TV when you trip. IMO TV sucks one's energy out, it's like it turns people into zombies.. If you're going to trip, a plant or even a wall should be entertaining enough that you dont need those flashing pictures to keep your attention.
Maybe try substituting TV for just some nice music, and have some nice art/psychedelic cloth or nature/plants to look at.. or just close your eyes. I think you'll be able to go much deeper and get much more out of the experience.
And regarding general suggestions and ideas, I definitely think you should read the links in the welcome PM you received, including the health and safety section, the FAQ and the WIKI.. That should be enough interesting reading/studying to keep you busy for a while, and you'll understand DMT and the processes behind its extraction and use much more once you do. Let us know if there's anything you dont understand after reading.
See you around!
