Thanks again for the replies

Crash, sounds indeed like I'm going through what you did a couple of weeks ago. I think I forgot to mention profuse sweating, but yeah - that's been part of it as well.
Jans is right about me and marijuana - I don't smoke. Actually, I think I'm gonna stay away from anything stronger than tea and just wait it out. Yesterday was worse than today so at least I'm over the worst of it. Hopefully, I'll be back in full force before the end of easter.
