Try .5mg clonazepam and .5mg alprazolam if you're intent on combining them. I wouldn't be, you seem inexperienced in both of them. In your situation, I would take 1mg alprazolam and an option of one .5mg redose, leave it at that. Re-dosing can get messy pretty quick, so I would avoid it.
Benzos are notorious for making you believe you are sober after the come-up phase due to a lack of euphoria, and leading to redosing due to disinhibition.
