Sassie, I haven't tried any other ADs. I was prescribed citalopram 20mg and it was way too much for me, I was really coshed by it.
The experience has left me terrified of taking any other ADs. I figured that if it was going to be a horrendous experience getting onto these drugs then how on earth was I going to get off them. I decided that I would try some other things first before trying any other ADs.
I do think I suffered particularly badly. They had an utterly sedating effect on me, not just sleepiness, but passed out unrousable for several hours within 45 minutes of taking one. I had extreme persistent yawning, irregular heart beat, zero appetite, poor visual awareness and perception, completely numb just didn't feel anything at all. My teeth hurt from clenching my jaw.
I just didn't care about the things I'd normally care about, little things like tidying up, keeping the house in order. Just went to rack and ruin for about a week till I felt normal again.
I need to drive and it became clear that I was not safe driving on these drugs. I managed to reverse my car into a lamp post even though I knew it was there and the sensors were going crazy. I was so numb though I just kind of shrugged it off.
I have been taking Kalms, 2 3x a day and that has helped a lot. When I went to my GP the DCs had had infection after infection and I caught the lot, I was really really run down and just couldn't cope.
Having said all the above, going to my GP was the best thing I did and it kind of gave me a bit of a jolt and even though the ADs were horrendous, I slept so much and did bugger all that I least my body had a rest.
It also prompted me to get back in touch with a therapist I used to see and I have been to see her and that helped enormously.
I'd completely lost all my boundaries and I had no idea where I began and ended. I was feeling enslaved by my family and trying to do the right thing the whole time. I was always procastinating and then feeling overwhelmed.
I've forced myself to make more time to do things that I like, eg I love to sew, crochet etc and I've done much more of that. I've also been walking more and trying to eat well. Made DH iron his own shirts 
Also, did your GP run any blood tests? Mine ran a whole raft of tests and I'm surprised to discover that I am anaemic and deficient in Vitamin D. Apparently this would have contributed to my anxiety and low mood. I'm due back at the GP in the new year.
