I have been taking MK4 for 3 days now first two days I took 1mg today 2mg, first day and second day I felt the annoying tickly feeling In my legs and arms but wasn't too bad, today with 2mg the feeling is worse, I've had restless legs feeling before but not for a long time so I'm sure it's the MK4 that has caused this, why would MK4 cause this?
