Your "Perfect Strength" Is...

Based on the answers you've provided, we've come to a conclusion...

That in your situation the Full Strength Oil (17MG/Serving) should work for you best.

This strength of oil is also very versatile in that if you consume 2x the recommended serving size (aka: 2 full droppers; the recommended serving size is 1 full dropper), it will be the equivalent of the Extra-Strength single serving size. And if you consume 3x the recommended serving size (aka: 3 full droppers), that would be equivalent to the single serving size of Maximum Strength. 

Another words, you have flexibility and control with this strength to experiment with higher strengths before committing to purchasing them to see if they work best for you.
