Feel tingly legs also before falling a sleep i will have quick jerks not allowing me to fall a sleep..what can cause this, ?

Restless legs: Seems like you are describing 'restless legs' which can easily be treated naturally rather than with the various medications on the market. You can start with a B12 and folate (folic acid) supplement as well as with a thyroid supplement containing l-tyrosine, iodine and selenium. I have seen great improvements in patients with this regimen. Its an imbalance of chemicals in our body which the above will help.

RLS / PLMD: Possible causes include restless legs syndrome and/or periodic limb movement disorder. Treatments do exist for both disorders - but i recommend a thorough evaluation by a sleep medicine specialist first.
