Minocycline Hydrochloride and medication

I am taking 100mg 2x a day of Minocycline to treat my acne. About 2 weeks after the start of this medication, I gained 10 pounds virtually overnight. I know it was that fast because I see a weight loss doctor weekly and I'm on a very precise diet and exercise plan and it I was fine until about day 14. I went to bed the night before and woke up the next morning with an additional 10 lbs. Right now, I've been taking it for about 6 weeks and have managed to keep the weight gain to a minimum average a week by adding additional workouts to my regimen for a total gain of 14 lbs. Although it's treating the acne very well, the money I've spent to lose 53 lbs over the course of a year just to turn around and gain 14 in a matter of weeks is extremely frustrating. I did not have this side effect with Doxcy, but sun exposure was causing severe burns so we switched meds.
When I return to the doctor in a couple of weeks, I will see if there is an alternative solution.

This medication did nothing for my acne. It gave me headaches, depression, moodiness, and hives. Save your money and do not buy this product!
