Risperdal?

Yesterday my doctor switched me back to risperidone after like 8 months on quetiapine, because I told him I grew completely intolerant to that pill and I was sick of having so many problems waking up and not being able to actually being awake after like 4 hours... anyways I am worried about weight gain like happened before but now I'm on a healthy diet and I started going to the gym last week, and honestly if I gain a kilo it's better than the quetiapine's inability of making me wake up. I took only 0.5 mg of risperidone last night (I'm starting with it) and I could wake up this morning (it's always hard for me to wake up though) but instead of falling asleep in the shower while getting dressed and so on, once I got up and woke up I felt awake inmediatly and when I got to work I didn't even need a second cup of coffee, and now I feel great. So much better than with quetiapine.
