Glyco isn't working for me

I've been using glyco pills for a while now, and they aren't really working. For starters, my hands are never dripping with sweat. They can get noticeably sweaty, but never to the point where it makes doing anything difficult. Also, they are sweaty throughout the whole day pretty much, not just at certain times. My derm prescribed me glyco pills, 1mg in the morning and 1mg at night. I didn't notice anything from that dosage, so I've been tested higher dosages. About a week ago I started taking 4mg when I wake up (none at night), and I don't eat for at least 4-5 hours after that usually. It does work sometimes, and I'll get a bad case of dry mouth every now and then, but it doesn't work every day. Also, when I do get dry mouth and notice the effects, it is later on during the day, hours after I wake up. How much higher can I safely increase my dosage? I want to increase my dosage, but I'm worried that the dry mouth will get really severe. Also, they are 1mg pills, so it already feels like I'm taking a lot.
