Thanks guys, sorry for delay, my computer connection has been up and down this evening
Well, all is OK. We spent 25 mins chatting to the vet as she wants to up his meds by 1 tablet daily as his Sodium levels still aren't at an acceptable level but his Chloride and Potassium ones are reasonable. Full bloods again in 2 weeks plus urine sample too. We are hoping that this extra tablet will at last stabilise him, although to be fair, his shaking has been minimal this past week. He is still occasionally doing no. 1's & 2's in the house (not asking to go out) but this may be because he's still not fully balanced.
Thank you all for your kind words and support, I know I worry too much

Here's hoping we will have him sorted in the coming weeks. Lesley x
