The last time I did pharma... the first time... I had some really uncomfortable sensations mainly in my neck. It didn't really occur until after I was coming down from smoking, and my i could not get this pain out of the back of my neck. It was strange, kind of electric feeling. It was on either side of my spine on my neck. I was very relaxed at the time, and coming out of a state of bliss but the uncomfortable feeling in my neck lasted for about 30 minutes. Any thoughts?
