Kureha, you have to take the meds for a sustained period. Taking them one day and not the next is not going to have what the docs call a therapeutic effect, it's completely predictable that you will be treatment resistant if you are taking meds like this. Why not pick a med that you can tolerate , and btw tolerance takes some work , gradual titration or taking the drug for at least a month as prescribed , should hopefully see you over the hump , until you can then tolerate the med and take a therapeutic dose going forward.
