At the very least you should get back the price of your materials. Most say two or three times the cost of materials, depending on what the economy will take. That will give you an amount for your time. You deserve a fair wage for your work. $20 for a full size afghan is much too little IMHO. You could probably sell a hat and scarf for that.
Doctors often prescribe statins for people with high cholesterol to lower their total cholesterol and reduce their risk of a heart attack or stroke. While statins are highly effective, they have been linked to muscle pain, digestive problems and mental fuzziness in some people and may rarely cause liver damage.
Switch to another statin drug. It's possible, although unlikely, that one particular statin may cause side effects for you while another statin won't. It's thought that simvastatin (Zocor) may be more likely to cause muscle pain as a side effect than other statins when it's taken at high doses. Change your dose. Lowering your dose may reduce some of your side effects, but it may also reduce some of the cholesterol-lowering benefits your medication has.
