Hello. I believe I can be of help to you with this issue.
You will have withdrawal symptoms similar to those associated with many opiates, though unless you have been on quite large doses of codeine, it shouldn't be that bad. You can expect a generally 'oppositional' reaction during withdrawal. That is, just about every effect you experienced while on codeine will be the opposite during withdrawl. Rather than muscle relaxation, you will experience muscle tension. Your legs may cramp up and you'll experience restless legs perhaps. You may also have trouble sleeping
; experience weakness, yawning, runny nose, sweating
, headaches, muscle pain and twitches, irregular heartbeat, nausea, vomiting, fever and insomnia
. You might want to talk to your physician about your plans and ask if you could be prescribed two medications to take and then taper from across the 4-7 days. These are clonidine and klonopin. They will ease withdrawal symptoms but you will need to have someone help you manage the dosing across these withdrawal days because your really cannot count on yourself to take the drugs safely. If you have no one to help monitor the dosing of these meds, then the cold turkey method is often followed by many people. The medications I mentioned lower your blood pressure and the second one primarily serves as muscle relaxant, and it can help you sleep. Tell you doctor you will certainly stop in a time or two to have your blood pressure assessed if he thinks the clonidine is a reasonable idea. He/she may or may not be up to speed on the different methods of helping patients taper from opitates such as codeine. I'll pause here and solicit your reaction to this post. I may not respond again until the morning as it near midnight here and I need to get to bed. Will respond to your post in the morning
