My story- help me pls

[goodison_blue]

I am 19 yrs old, and have been playing poker for 4-5 years... I have had a relative amount of success live, cashing in a few tournaments since iv been 18, and won at least 50% of the tournaments that I have played in with friends- usually about 8-12 playing.

Online- I have done well on occassions- but I have a massive problem- tilt...

I have read many poker books, and understand the key concepts in poker- I have been a consistent winner at up to 1/2 blinds/... however, when drunk/ on tilt after a bad beat.... i always go on higher limits or play awfully and blow it all. Twice in the last month iv deposited, built a roll through hours of play... and blown it at 3 am on tilt or pissed...should i call it quits now and just play live?

If im always blowing it is it worth it?

So my question to all you experienced players- is do I stop playing online, and concentrate on live? or is there some sort of software that blocks you playing a certain blind level...

im so fustrated cos i have built this last roll up over 3 weeks, moving from 25 NL to 100 NL, and then i go and blow it last night after 3 horrible beats.

Anyone who has been in this situation and been able to turn into a winning player pls give me some advise!
