So day before yesterday (on day 8 for me) I was feeling extremely tired/weak, almost flu like symptoms but without the sickness. Also my dick was shriveling up, I could feel it going back inside. Like my balls feel smaller for some reason. Today I'm feeling extremely lethargic. I slept for about 9 and a half hours and still feel sleepy. Plus my back is aching for some reason. Is this flatlining or withdrawal symptoms? My addiction wasn't as serious as a lot of people here but it has affected my life too. So any help would be appreciated. Thank you.
