For the last week, literally since Tuesday, I slept on average 20 hours a day - just couldn't wake up.  So I decided that it's ridiculous, and lowered myself a doze of diazepam from 8mg a day to 6mg a day (stopped taking the morning 2mg - stayed on lunch 2mg and night 4mg).  Felt a bit better yesterday, i.e. although I wasn't able to do much, I could be at least half-conscious on the sofa, and only doze off every so often, but I'd say I slept some 18 hours in total.  Today was even better: managed to have two students, so 4 hours or being actually awake sufficiently to teach the language! Big success.  Mind you, finished the last class at 6.30pm and woke up at 2ish am, was so exhausted.  But still!

The only downside is that I already feel the difference in pain: maybe I shouldn't, because the 2mg of diazepam is just a drop in the amount of medication I take - the painkillers and muscle-relaxants - but I feel it the most in the right shoulder (which my physio tried to get to work last Monday, but all my home efforts in exercises ended up in odd clicking noises and even more pain) and the neck.  Another session of physio tomorrow - we'll see what happens with the damn shoulder then...
