Could possibly, yes be withdrawal symptoms and not all medicines will take your withdrawal symptoms away. I have been addicted to Percocet and Vicodin for 2 years, I detoxed in Oct 2006, Relapsed and here I am again. I am on day 4 of no pills. I have had headaches, nausea, feeling like Im going to vomit, my whole body feels like I got hit like mac truck and I have no energy. Most say that withdrawals are like having the flu. I would suggest keep taking the Phenergan because thats what I have been taking also, well Promethazine, its the same thing!! and also I have been taking Xanax for sleep and anxiety. My doc prescribed me Clonidine for the withdrawals, its been working OK but not the best. We just need to get through a rough couple days/weeks and everything will be okay physically. Mentally might take a little longer. Take some HOT HOT baths too, that works well for body aches, A lot of people on here told me to do so, and it has helped!! Hang in there. You can do this, We all are!!!

Sounds like classic withdrawl my dear. Like Smiles says, it's a lot like a really bad flu. 2 months is certainly long enough to become chemically dependent, aka "addicted". Hang in there--you'll get through this, but it may take a little longer. Can you take some time off work? Perhaps the doctor who prescribed the pills can give you something else to ease the w/d. Give him/her a call.
