What psychogenic medications are you taking that come in dissolvible and non dissolvable form? I've never heard of that. Is there a reason you must take the medicine dissolved? (like it's difficult for you to swallow pills?) Did you have to go through some rigamarole with your insurance to get your drugs in this form? (like a letter from your doctor?) If not then they may not care. You can ask your mediative insurance provider (your HR if you get it through work). But if you're pretty sure they won't switch back then you've answered your own question "It's not worth it."

Personally I'd choose the trip with my parents whatever the cost.
