I can't think straight at the moment. Its hard to keep my eyes in focus, though optician checks show my sight is OK. My head feels like I have a permanent hangover. I can't keep my head and neck straight because of pain, but if I let my head droop forward (especially in evening when sitting in armchair) then I get really woozy and can't keep my eyes open or stay awake. It feels like I am totally drugged, though I really don't think the list of meds I'm on should do that - its just diclofenac, baclofen (for muscle spasms - have been on this for 4 years now so should be used to it) paracetamol and codeine for pain. I've slowed down on the paracetamol and codeine and rarely take it during the week now to try and keep my mind alert for work, but its not making any difference.

Can neck problems really be doing all this, or is it something else that is mucking up my brain?
