MSM resulted in skin and other problems!

I started using MSM powder in late January... it has resulted in a very dry, flaky scalp and hands. The skin is not only flaky and dry, but feels very slippery and static and I hate it. My hair has never looked this dry and dull. I eat a healthy low-carb diet and haven't had dry skin and scalp problems this bad for 3 years while I've been on the diet! The hair also feels brittle and extremely dry and that's not funny because I'm balding anyways.

The other thing that MSM did was make me very sleepy and also made my knees hurt a lot. How long does it take for MSM's effects on hair and skin to disappear? I've been off the stuff for 9 days but no big improvements yet. Well, the sleepiness has ceased somewhat.

Anyone else had these kinda skin and hair problems with the msm? How long does it take for the MSM to diminish from the body? I hope that I'll recover from this shit, I'm feeling pretty shitty now. Could this be detox symptoms? I started with like over half a teaspoon (2-3 grams)...
