was diagnosed with severe depression. she prescribed me lithium carbonate 300mg 1 capsule in morning and 2 caps at bedtime also venlafaxine hcl 100 mg take one and one half twice a day for anxiety and depression. also bupropion hcl 75 mg twice a day fordepression and anxiety taking the lithium for mood stabilization and depression. My question is does anyone think this is to high of doses or should I start at a lower dose and work up to present dosage?
