How long before you second guess yourself.

I've been playing for a living for a little over 2 years, mostly live. Expenses, expenses, bad money management and expenses forced me to start from scratch last January. Since then I've been playing mostly online. I finally got myself up to 5/10 about 6-8 weeks ago and began making $40-50/hr. I think I've been running a little to well for most of that time. Occasionally losing over a grand at a time, but usually making it back within 30 hours or even the same session sometimes.

But now those convenient upswings have dissappeared. I don't even make small wins anymore. I'm down about $1000 for the last 8 days (6-9k hands). The volume doesnt concern me so much as the duration.

I'm getting very concerned and today in just 450 hands I've lost $450! My bankroll isn't in danger, but how much longer can I let this go on?
