I'm really struggling with sleep at the moment so I'm hoping someone can help me. I'm not sure what's relevant and what's not so I'll try and include as much detail as I can.
It started off where I would have a bad nights sleep every few nights, normally I go to bed early and I'm asleep by about 10 ish and get up at 7 but I started waking a lot more than usual in the night and then getting to sleep later. Now I have an ok nights sleep every few nights and rubbish the rest of the time, maybe 3 or 4 hours sleep a night.
I think (but might be wrong) that my sleep is like it is because I'm so restless and fidgety all of the time. My skin feels like it's crawling unless I'm moving. I can lay in bed and try and stay still but all of a sudden have to move my limbs quickly of jump up out of bed or do star jumps to get rid of some restless energy. I feel like this through the day too.
I was on sertraline from November to a few weeks ago. This restlessness started while I was still taking it and at the time I thought it was maybe the tablets so thought when I stopped taking them it'd stop but it hasn't. Not sure if this is relevant.
I have a juice plus shake on a morning for my breakfast. I don't want to get in to the ins and outs of diets if this has nothing to do with it but I thought I'd mention it in case anyone is aware of anything in it that could be causing this.
In a few weeks I do have exams so I know I'll be worried about them but I don't normally react like this and I'm struggling to revise because while I have physical energy I have absolutely no mental energy because I'm so tired.
I think that's everything but any questions let me know and I'll try and answer them, I'm just really hoping that someone can tell me that they've had similar or know what I have or that the doctor will be able to help, I REALLY need my sleep 
Thanks in advance of any help.
