Portland, that is one of the problems in trying to play a drawing opening--your opponent may not fall in line with what you want to play and then you can be in trouble...
To improve your chess, one way is to learn to put pressure on your opponents and if one plays a drawish opening that they do not know very well--there is little pressure on your opponent.
d4 d5 is fairly solid, the regular Slav especially, and the Queen's gambit somewhat.
Otherwise 1.d4 Nf6 2.c4 e6 leading to the Nimzo (Nc3 Bb4) or the Queen's Indian (Nf3 b6)
