Definitely!
I've been on ADs for 25 years, I think. I don't expect to come off them. They did save my life. After several unsuccessful prescriptions, I ended up on 450mg Venlafaxine. A few more life reversals and I was suicidal again; shrink added 30mg Mirtazapine. That was as close to a magic bullet as one could hope. Since then I've dropped the Venlafaxine by 75mg whenever I feel brave enough, and always in late Spring so I can get a nature boost while trudging through the deficit. I'm now down to 150mg Venlafaxine and the 30mg Mirtazapine.
People tend not to get that a big part of treatment is learning to live with depression - the meds are for taking the edge off. When you break a leg, you can get meds for the pain but your leg's still broken: you can't walk on it and it still hurts. It's a similar deal with ADs; they are symptom relief, not a cure.
It actually sounds as though you're managing your condition quite well - part of that, of course, is knowing when it's getting worse. It's very reasonable to try different meds and/or different combinations when the current ones aren't helping.
I'd rather like my libido back, but not enough to risk 'going back down'! When you need help, ask for it
Please remember to be good to yourself, eat, sleep, all that. x
