@kiwiMark I have this problem a lot too. One thing I tried last session was doing some poker "homework" (3-4 different hand situations) and really taking my time and talking out the range/moves I would play and make for a good 10-15 minutes. This got my brain in the thinking mode from the get go and as a result I played one of the best sessions I have in the last couple weeks. Also maybe a set music playlist (some easy to listen to electronica or something) for grinding could help.

That said, m2m and Jason's first posts = my poker career.
