I was prescribed Lyrica (75mg) for sleep and anxiety disorders (caused by burnout) and took it in the evening for about a month (with a few/single days off). This actually improved the anxiety/tension and I was able to sleep through the night for the first time in a long time. However, since Lyrica not only caused me very severe headaches, but also a permanent feeling of being "beside myself" as well as many other side effects, I slowly phased it out by breaking open the capsules and reducing their contents more and more (first in halves, then in thirds, in quarters...).
This has worked reasonably well and I have even been able to sleep through 2-3 nights since my very last dose a week ago. I do have some complaints that have returned since I stopped (or were triggered by the withdrawal) - but all in all I feel better and more comfortable than when I was taking Lyrica.
However, for the past few days I have been experiencing nausea, which occurs several times a day for no particular reason and then disappears again, as well as (not frequently but nevertheless) a feeling that something is brushing against my scalp (kind of like a bug crawling over the hair on your head).
Could these still be effects of the pregabalin withdrawal? I had switched from taking 18mg four times to 0mg a week ago - surely the drug should have left the body by now? Or has the drug already caused neurotransmitter release to be "reprogrammed" after such a short intake and the neurological processes now have to recover? How long do I have to expect withdrawal symptoms in this case?
