Please be really careful about swapping meds as quickly as you have been - yes I know it feels like a long time. But most anti ds take at least 4 weeks to get into your system. Then every change - upping or dropping - takes around the same time to have an impact. So although you've been on them for what feels like a long time, you actually haven't been able to give them a decent time for each change to have an effect..
Also, please, please, please don't change any more meds until you are able to speak everything through with your Dr...
