Hey, Odee. I take Trazodone at night as a sleep aid. I take 50 mg. As far as I remember that's the only dosage I've taken. I'm not sure how effective it is anymore. I really need to talk to my psychiatrist about it. I haven't noticed that it perks me up during the day. I went off Ambien a good while back when it seemed not to be working any more.
I can't take many ADs because I am bipolar and they make me manic. I also take Wellbutrin, though.
As far as Lamictal, I was on the highest dose for years and years and it evidently became toxic to my body. After a certain dosage, the effects aren't improved. Maybe that's where you are, so your doc doesn't think increasing it will help.
