I've completed about 9 weeks of low carb. I'm taking calcium, magnesium, potassium and a multi-vitamin. I started about 3 weeks ago with the first bout of lightheadedness -- had no problems with induction -- and now am experiencing symptoms once or twice a day, especially about a half hour after a meal. I'm on thyroid meds (my thyoid is gone from thyroid cancer) and on blood pressure meds. I drink lots of water.

My doctor is not supportive of low-carbing anyway and suggested WW instead (I have trouble sticking to WW).

I have lost very slowly over the past 3 weeks -- barely a pound a week.

I'm 50 and female.

Any suggestions?
