I hate it.

If you are worried about being outplayed everytime when you enter a pot move down in stakes until you can win and learn until you are good enough and BR enough to play higher stakes.
Im sure you make as much playing $5 at 5NL than $5 at 25NL because the players are so much worse, and you certainly get less varience.
you are also more likely to learn faster as you are actually playing flops.

In short... pfffff

If on the other hand you have just lost alot then it might be profitable to go allin straight away on a good hand (QQ+) because someone might think you tilted and call with KQ , 22 or something. Id rather take a break and come back with a full stack when im ready or just rebuy and carry if im feeling ok about it.
