You are still on a low dose so I would not worry so much, someone very close to me takes 150mgs., and she has never had a problem and takes more than one medication, including NSAIDs, etc.. Having said that, we are unique so medications affect everyone differently (benefits, potential side effects, interactions, etc... )
Always check with your Dr. or Pharmacist before you take any supplements, or any other medication, it is important not to self medicate and also not to worry so much to the point that it begins to stress you out , you need to take your AD and try to enjoy life a bit, stay away from alcohol, not even one beer, alcohol, as you is a depressant , and you do not need it, I have not drank a single drop of alcohol for 14 years.
All the best,
