I'm Taking 50 Mg Lamotrigine In Afternoon, Then At Night

I'm taking 50 mg Lamotrigine in afternoon, then at night for sleep-1 clonazapam and 100 mg trazadone. I wake up weak and dizzy. The dizziness is on and off all day, memory is way off, low blood pressure of 93/58, muscles are weaker than a few months ago even though I've been taking these for over a year except I've increased the trazadone from 50-100 this week and lowered the clonazapam from 2 to 1. Is there anyway to increase blood pressure? Or to feel stronger like I did a year ago? I lift weights and do major cardio workouts. Thanks
