Ah, ok - well if it's control of the lucid that's not something I'd blame on the Galantamine. I can tell you I've had lucids where my control wasn't exactly up to par as well. I think it's really a matter of confidence and expectation.

You can be lucid in a dream and assume that you have control because you are lucid, yet you really have to expect to have the ability to make changes in your environment to the point where you have to almost see the change happening or completed just as you're thinking about it. It's weird.

For example, I usually RC by trying to levitate off the ground. For this I jump up lightly and expect to stay afloat - but, that doesn't always happen UNLESS I focus on the feeling of being afloat. Then the action of actually levitating will follow. It's like you need one to inspire the other.

This sort of makes sense if you think about it. You're really not experiencing anything you do 'out there' in the world. It's all happening in your head (or non-physical realm). So, naturally everything you experience must be rooted to your thought/emotions.
