Mid July....when did this happen???

I cannot believe it's mid July already, I feel like we just celebrated the 4th.  The older I get the faster the time goes.
So life has pretty much been the same old lately, nothing dramatically new or anything.  Noah is finished with Pre-School and as of June 9th is in Pre-K.  He seems to like it, during the summer they go on a few  field trips, so he has gotten to go to Lake Tobias and just today they we wnt to Let's Pretend, then to Hoffer Park for a Picnic and to play for a little while!  He had fun! 
I'm still having behavior issues with him.  We were to the behavior specialist 4 times, and it did seem to work until after the 3rd visit.  Literally we left there that time and a switch flipped and he was not only normal but WORSE, so Monday when we went for the 4th time he seemed to not know what to say to do.  So that kinda made me feel at a loss, I mean this boy is smart, too smart for his own good maybe.  He started talking ADHD and medication and all this, and I'm sorry he's 4, my son is NOT going on medication.  I mean do not get me wrong I get it if they need it they need it but NOT at 4.  So I sat down and made a Rules list and Chores list.  After his bath last night my Mom and I sat with him in his room and went over them, told him that it was going to start in the morning. 
First thing this morning......perfect, got up talked nice, got himself dressed, everything great....until we left.  We go to get in the car, to go to school, he decides in stead of getting in his booster seat he's going to put down the middle of the seat and climb through to the back.  Yeah this was the "fight" at 7 this morning for 5 minutes that SHOULD NOT have happened. 
Had a perfect day at school, purple card (yay), then Grammy took him up to Aunt Joann's after she got off work to play with Antonio for a little and they didn't come home until 6.  Also was perfect there as well, then he came home and had a few incidents, one in particular was BAD kicking screaming knocking stuff over, acting like a maniac, you couldn't talk to him because he was being loud.  So what does Mom do?  Pick him up and carry him to his room, and tell him to stay there until he's done, he said he was done so I tried talking to him a little bit about it  Then we get a bath and he is all better!  Went to bed around 8:45 read 3 books he had me get on my kindle and he was out like a light.
I love my son and there is nothing that I wouldn't do for him, including get to the bottom of what exactly is  going on with him.  Is it just a behavior issue, is it ADHD, is it a Depression thing, what EXACTLY is it???????  I don't know, it makes  me sad.  I just want to figure stuff out.  That's what I have been trying to do since April....but apparently we have back slided somehow.  I don't know.
