Lorcet (miss the blues so much) were my daily breakfast, lunch and dinner for 2 years .. until I got an ulcer, then they switched me to Norcos, which still was crap and then upgraded me to something stronger later. My stomach hurt for months on this medication so if you were doing that much a day, it's possible the tylenol has caused some stomach issues. (get that checked)
Once you're past the sniffles, leg aches, tummy upset, etc. and past that first 3-4 days, it's still a battle, but you can do it. Even though all of us have the same withdrawal symptoms, our bodies are different in how we adjust after withdrawal. For some reason hydro withdrawal gave me the worst sniffles, even for like a week after withdrawing, and more so than oxycodone.
Congrats on trying to stay clean .. wish you all the best. xox
