All of the side effects except weight gain will eventually subside - at least, in my experience with Seroquel. As for the weight gain, Seroquel is notorious for causing weight gain. It's a very difficult situation because it seems that most people, when on Seroquel, feel very hungry (and tend to crave sugar) but exercise is difficult because at the same time one feels sleepy and it can be hard to move much.

Hopefully, at such a low dose you won't have an issue with weight gain. Do the usual...watch your portions, eat protein instead of sugar, drink water, sip tea, chew gum.
