I Have Been Taking Minocycline For A Couple Of Years

I have been taking minocycline for a couple of years to treat rosacea. I am now reading that it causes weight gain, which I have gained about 20lbs since being on the medication and can't seem to lose weight no matter what I do. I also read that minocycline should not be taken long term. Should I stop taking the medication and take a probiotic instead?
