My advice is sinple, play more live than online.
As long as you dont mind taking chances with your roll. I wouldnt advise playing those stakes live under rolled but if thats what you want and you dont mind the risk then continue on.

Make sure you get your online coach to discuss the importance of table selection. Find a table with fish and start there. Dont sit at a nit table.
I dont want to be rude but if your getting consistently cooked at online, you need to go to the lowest limits and start from scratch. You need to remember that at the smaller stakes, many people dont care about losing their $5....they are there just for shits and giggles and perhaps will not play as scared as some at a 2/4 live table where possibly the majority of them cant truly afford to play.
