Of course its the pot causing your issues, you said "sleepiness nights where I don't know who I am and I can't comprehend reality etc".
I can speak from experience because I was also a daily pot smoker. I quit cold turkey one day and I haven't missed it, I might have had a couple of cravings for it but they weren't huge omg I'm gonna-die-if-I-don't-smoke-cravings. They were more like "huh I could really go for a slice of apple pie right now but I don't have any" cravings and eventually those stopped completely.
Smoking pot on a daily basis can have mental ramifications. It caused me some pretty weird moods some nights and even sent me into a total panic attack. It can sometimes cause dissociative feelings or detachment from reality. It can cause a host of other things if you smoke in excess. I am not against pot useage if it's legal and you have a medi-card, which I did...but doing something like that on a daily basis is not a good idea for many reasons.

Yes I would say it has a lot to do with the pot.
