Hi again Bo
as you have been prescribed how often to take it, it may be worth arranging a few days, or a week if you can manage it, where you can take it as prescribed and not need to drive etc if they make you feel drowsy. This would give you a chance to see if the side effects wear off or not. if they don't wear off, it is then up to you to decide whether the side effects are worth the pain relief (oh, the joys of balancing pain relief with side effects) or whether you need to change soemthing.
I definitely aggre with blaady, codeine is well knwn for causing constipation, in fact I can't take it because of it, but for most people it cam be managed with diet and or meds like lactalose, if the pain relief is good. Let us know how you get on.
