So I switched from ritalin to vyvanse. I'm currently on day 6 of elvanse. My skin is really dry, I have dry eyes, dry and cracked hands, cracked lips. My body is itchy af too. I've been trying to stay hydrated but it's not doing much. I don't know what to do because I wanted to go hiking tomorrow, it would be like 8 hours, 300m elevation so not much. My intuition is telling me that 20 degrees Celsius, and full sun will most likely make me even more itchy, I'll sweat and the hike will be a nightmare.

Am I correct here or am I overreacting? I've been chugging water and electrolytes, used up like 1/3 of hand cream bottle today just for my hands but my body is still dry as hell.
