Thank you all for your replies.

I have nightmares every night on it. But that's the least of my worries. I started having palpitations. I thought oh well it will go away but this morning I almost passed out whilst taking a shower I think I had tachycardia and my blood pressure dropped. I phoned NHS24 (I live in Scotland, UK) and told me to not take it today and phone my GP tomorrow as I might need to change pills. I am disappointed. This pill seemed to not sedate me and work ok so far even from the first few pills. And now I probably need to change again.. how long until I find something that agrees with me
