No matter what I do I can't get to sleep.... again! The last 2 weeks I've felt like I'm being punched in the kidneys every 10 minutes. I have absolutely no apetite and the only thing I can do to sleep is get watered! I'm on tomazapan from the quack and they just make me hyper so I've stopped taking them. During the week I have to be up at 5:00am for work and I'm awake at 3:30am give or take 10 minutes. I can stay up drinking till 1:00am and I'm still awake at 3:30am. I'm sitting here wide awake now although I don't have to be up in the morning I can guarantee I'll be awake in the wee smalls. This lower back pain has no cause as far as I can tell as I don't really lift anything heavy, I'm just on my feet for a long time (never still, but moving around).
I've got another appointment at the quacks Tuesday morning, I just wish I could sleep. 2 hours sleep a day (if I'm lucky) is just dragging me down.
Tonight (so far) I'm down 6 cans of fizzy yellow stuff and a half bottle of bells and still wide awake!
If I go to bed I'm just staring at the glow in the dark stars on the ceiling and will be for a few hours yet. I'm not asking for a diagnosis just venting a bit. Sorry. 
I have some empathy with your predicament, but not sue you should be drinking with your medication at it is supposed to give a similar effect to alcohol.
I have rouble in getting to sleep, the mind starts and that is that, my solution is similar to yours, whisky. Though once taken I sleep through, mostly, but have to have the right amount, too little and does not work, too much and peed. For day to day use I buy 1.5L bottles from the supermarket, use a little water to make the drink longer.
Appetite is a massive problem for me, since my illness weight is a problem, have huge problems in trying to keep it up, weight

So you have my understanding mate.......

I never drink and drive, but I do sometimes wonder about the next morning
