The waiting and wondering can drive you nuts, yes. In that light, I'm going to make a few comments that might ease your mind.
First--of course profound weakness and not being able to do something as simple as squeezing toothpaste is a sign of ALS--and about a hundred other things as well.
Als can progress slow--but your post sounds like these issues have been in a matter of a month or two. It's not normally that fast.
Neuropathy and myopathies can ONLY be diagnosed with NCV and EMG. Muscle weakness can have a multitude of causes. Als is only one of them. not all of them are even related. Sometimes, it's within the muscle itself, as in myopathies. Other times, it's within nerves, as in neuropathy, trapped nerves in the elbow can affect the hand, believe it or not.
Twitches 'all over' are not normally seen in ALS. The fasciculations in ALS happen after damage has been done. There is actually usually some level of atrophy by the time it presents. Stress over wondering about ALS can even cause them.
Same with Bulbar (mouth) issues. If it started, for instance, distally, in your dragging foot, it would take quite a while normally to reach the bulbar region, for instance. Oh, and for foot dragging--that's normally constant, not just 'sometimes'.
We have a saying here that's in my signature...it can only be ALS when it can't be anything else. You still have a LOT of 'something else" possible here.
Even a history of drinking for years can cause imbalances in your system that can screw up muscles and nerves.
Try to relax and wait for the EMG
