just a thought - about the internal shakiness. it is possible that you have an allergy to gelatin. SF722 is in gelatin capsules. i was getting internal shakiness everytime i took fish oil in gel caps-3 or 4 caps at a time. i thought it might be an allergic reaction to the gelatin or fish oil, so i stopped those. i noticed that every time i took anything in gel caps i would get this horrible internal shakiness which made me feel like something was really not right. i was a little frightened by it thinking that i might have some nerve disease like parkinsons. i stopped the gel caps and the shakes stopped. i did some research and found that gelatin contains glutamate - as in monosodium glutamate. this is an excitotoxin which over-stimulates the nerves to the point of burning them out sometimes. i have not had the terrible internal shakiness since i stopped taking all supplements in gelatin caps.
