Just started 3/6 and I am on a 150 BB downswing.

I was beating 2/4 after 35k hands at like 2.5BB/100. I recently won a step 5 tourney and had the bankroll to move to 3/6. For the last 1500 hands I have lost 150+BB. Now, this has scared the crap out of me; I don't know if I should take some time off and re-evaluate my game or move back down to 2/4, or if I should stick it out at 3/6. I know a 150BB downswing isn't huge but it just seems to never end. any suggestions would be greatly appreciated. I am not showing my PT stats for 3/6 because I donno how helpful they will be after only 1500 hands. If you want to see them regardless, just ask and I will post them. TY.
