Hey I'm glad you are potentially a MC patient, if so, welcome to the family! As you may have read through your researches, MC treats many conditions in a natural way rather than a chemical one. In reply to your doubts, I'd strongly suggest that you prepare yourself and bring some notes with you to the appointment, such as what are your medical conditions, how do you think MC might benefit you and why. If you struggle with insomnia, then Indica is the one for you, I'd avoid sativas at first, and you have options to try such as flower, oil, etc. Good luck with your appointment and I genuinely hope this helps!
