If the bad streaks are killing you you're playing too high of limits for your money.
I recently started making around $100+ a week play $.50/$1 NL Hold 'Em. Course where I play, everyone is an idiot. I play at Royal Vegas
. I took the ten dollars they gave me and have brought it up to around $500 in a couple weeks.
How long have you been playing also? I played for about a year with no profits (internet that is), but have just the past couple months actually started making money. I've heard some people take even longer than that, I just catch on fast.
Hope it helps.
