Hey Baby_Sham, good work, keep going :-) Glad to hear you have started the tablets, they will really help and you should start getting some good night's sleep soon. The sweats will start dying down, not straight away, but soon, trust me.
If you're partner is out all day, find lots of stuff to keep you occupied, especially at times of day when you would normally have a drink - update your CV, have a look at ideas online for decorating a couple of rooms in your house (not right now, but whilst you have a bit of time of in a week or two), (sometimes staring at the telly can trigger 'missing' having a drink in your hand) so, do puzzles, read, garden, paint, sew, - get creative! You'll be amazed how many talents you have now that you can start focusing on things again :-) any last of all, take it easy - don't feel guilty for not being at work right now. You are 100% doing the right thing.
Hope you have a much better day today, and keep chatting xxx
