the main reason for swapping antidepressants is in the hope of chancing upon one that works and has side effects that can be coped with, its mostly guesswork....
L and W are different types of antidepressants so heres hoping
re K and A, these are both valium type and similar, none of these meds are stronger or weaker, it all depends on the dose, the only real difference is that some last longer
K or any other benzo that makes you sleepy when you dont want to be, is obviously taken at too high a dose, the sedation effect of benzos is different for everyone, you should have split the tablet to reduce the dose
stay with that doc as many others refuse any benzos for anxiety, insisting on an antidepressant only
the hope is eventually an antidepressant will be found that works for your anxiety and has side effects that arent too bad, then your benzo intake can be reduced and no longer taken every day
