Detox day 1

Just an update it's my 4th day and i am surprised i haven't been in more distress?
I have had diarrhea for the 2nd and 3rd day, my appitite has been ok eating almost normal (actually wanted to lose some weight lol)
I dont really have super cravings at this point. I did dream pretty heavy on the 2nd night but nothing extreme. Last night i didn't get my normal sleep but it wasn't to bad. I do have a bit of an ache or tension on the back right side of my neck that seems to come and go.
The one thing that i am a little worried about is when i spoke to a friend who i have been smoking with for 18years i had a bit of a panic attack when i was telling him what i was doing. I dont recall ever having that before?

Is it possible that after 18 years of very heavy use that i might have it easy?
I was in the process of cutting way back on the cigs but i have choosen to smoke them until i have the pot out of my system...

Also i have been reading that day 10-14 is tough?
Is it possible i will have an easy tranition or my body isn't withdrawing heavily quite yet???
Any info or advice would be greatly appreciated!!!!
Good luck everyone!!
