It definitely can be hard with the changes of medications and could be the reason.

As for the meditation, I only really use it when I can't sleep. I found that trying to force myself to sleep just made me even more anxious so it was better to get up and do something else, or try to focus on something else other than the fact that I couldn't get to sleep. As well as meditation writing helped me. If I got up for 30 minutes and wrote everything that came to my mind I found that it was easier to try to sleep again as the thoughts weren't spinning around in my head - they were out somewhere ready to be dealt with in the morning.

I don't have time to type out the different things I do for meditation right now (about to head to work) but I have found that different things help depending on my stress levels. This website gives a good overview of a few techniques - http://www.huffingtonpost.com/2010/0..._n_676353.html

Sometimes if I am just tired but not too stressed just breathing helps, other times I use guided imagery. I used to think that it was useless and couldn't understand why people meditated but some nights it really does help me. Not always - I still have bad nights - and it does take time to get into but over time it has helped me.
