I realize some people go through terrible withdrawals from opiates, and that compared to them, my withdrawals were no big deal...but it still sucked for me--
I abused fentanyl patches for 3 weeks straight..no time off, not even to sleep. I had 14 patches, all of them were mylan 100mcg/hour. Sometimes I would wear two at a time, a couple times i wore 3 at a time.(One new, one 1 day old, one 2 days old). each patch is supposed to last 72 hours, and I used up 14 of them in 3 weeks. When they ran out I went through about 3 days of withdrawals.
At first the withdrawals started like i always go through after eating percs for 3 days... mild coldsweats, little runny nose, slight burning in my lower chest, body feels just heavy, senses like taste and smell are dulled. (After a perc binge, I can drink a few beers at this point and get some sleep.) After about an hour of these initial symptoms, my digestive system came back to life with a vengeance, severe gas pains, heartburn, rectal burning when I took a shit, and pretty powerful nausea. Thats when my skin started to crawl. If you have ever experienced RLS (restless legs syndrome), then you know what I mean, but this was all over my body, not just my legs. It was even inside my body, like inside my joints, elbows, knees, and even in my lungs. Sounds odd, but thats the only way I can describe it. It was like I had to keep moving every inch of skin, and all my limbs too. The skin crawling was the worst of it and it lasted for almost 14 hours. It wouldnt let me sleep, or get comfortable, I had to move to a new position about every ten seconds. This was combined with the gas pains, nausea, headache, coldsweats, runny nose, and body aches, as well as feeling physically heavy.
After the skin crawling stopped, I had been off the opiates for about 16 hours or so, and was completely exhausted. (The patches made it hard to sleep so I was already sleep-deprived when I kicked) I drank a couple of beers and slept like the dead for 2 days. I woke up now and then, ate something or drank something, then went back to sleep. The coldsweats lasted the longest, and the runny nose stayed with me till the third day, but the nausea and headache disappeared sometime during the skin-crawling.
What did I learn? I will NEVER do it again, and I now have more compassion for long term heroin junkies who kick. I understand that they can and do go through much worse, and I hope to god I never have to.
