I cannot come to a clinical diagnosis for you over the internet
Your symptoms would be atypical for ALS and this sounds unlikely as a diagnosis
ALS usually starts with one limb before involving other limbs over a period of months. MS can involve any part of the central nervous system, so could be present both sides at once.
ALS causes weakness by causing degeneration of the motor neuron cells in the spinal cord that control our muscles - so it can cause weakness of the muscles. However a multitude of other diseases can cause 'weakness' - it is a very non-specific symptom on its own. Fasciculations are rippling movements in teh muscles that are a result of dysfunction of the nerve supply to the muscle - so they are also non-specific and can be caused not just by ALS, but also by pinched nerves, cold, exercise, and even certain medications.
I'm not sure what else could be causing your symptoms with just this information. It could even be muskuloskeletal rather than neurological, or a myopathy (especially if you are on, eg, a statin drug for cholesterol lowering).
The brief jerks can be non-specific and happen commonly to normal people, especially getting drowsy and waking up.
For reassurance, a visit to your local neurologist who can evaluate your symptoms directly and examine you, would be a good option.
Good luck.
Thanks
