Boofing and Med questions

Hello all!

Question 1 I’ve just recently gotten into Tina and have only done it via boofing my question is how much should I be taking? When I got it I was told what “chunk” to use I used that one and felt nothing. So the second time I took double and I really didn’t feel anything crazy.

Question 2 I take 70mg Vyvanse and 40mg of prozac daily. On days that I know I wanna get lost I don’t take them. But will having residual medication in my body affect the effects of Tina and G?

Question 3 I’ve been taking G for almost 2 years but unfortunately I think I’ve built a tolerance to it because I need to take 6-7ml to even feel it. Will I ever get back to the time where I could take 4-5 and be high for hours?

Thank you for taking the time to read and respond. This is all coming from a very inexperienced person who just wants to be safe and doesn’t have anyone to ask.
