Small profits in 1/2

So i was playing .50/1 and lost 1 buy-in of $50 almost immediatly then won some back, up and down small amounts.

In the end i got fed up and started playing 1/2. Made my $50 back and hovered around $220 for ages (deposited $200). I got upto $300 at one point but then went back down. Then i won a huge hand all-in on the flop of 478, i had 88 and he held 77. Took down $450 there, only to lose quite a bit of it a few hands later :/

Ended on $350 so still a profit of $150 for the day :)

Bankroll: $350
