I got on Phendimetrazine approximately a month ago, and I've lost 15 lbs. I got birth control today (Ortho Tri-cyclen), but I'm afraid to take it because I'm afraid it will affect my weight loss. I'm not worried about getting pregnant because I don't have sex often at all. I'm just getting on birth control so my periods will regulate. It's not a MUST have thing. Has anyone mixed these before? If so, did it make your weight loss slower, make you gain, lose quicker, etc?
