Yeah it's not pleasant. Never got cold sweats I'd imagine that would be very uncomfortable. My dreams tend to revolve around either trying to get some, having wasted some, trying to get away with doing some, and sometimes just going all out crazy on it.

I find myself still trying to imagine what it felt like, when awake during the day. Or I'll watch movies and be like "yep that dude is high a ****".

Some people have a harder time with it than others, but that doesn't mean weakness. It could be lots of things - dopamine deficiency, impulsivity, needing an escape from life situations, even just being at the wrong place at the wrong time or connecting getting high with other normal tasks and normalizing the destructive behavior.

At the end of the day, everyone can be taken down by drugs unfortunately.
