Ok so I've been on Prozac for two weeks and the racing heart and insomnia in middle of night are driving me crazy. The doctor has given me beta blockers to hopefully help the sleep and also more sleeping tablets but to try each separately. Does anyone have experience of BBS and Prozac? Is it likely that this agitation/insomnia WILL lessen? I think that I feel less depressed and less angry/irritable but hard to feel better when I'm awake from 2am every night. Help!
