See if it was up to me, and I was in your shoes, I would maybe hold off on taking them altogether until you get your shit straightened out a bit more. Otherwise, I'd maybe shoot for a lower dosage. I dunno, mushrooms are pretty unpredictable, and if you're in a rough spot in life then they will send you on an introspective journey that may be intense and overwhelming and terrifying and one you may not be prepared for.
I mean in the end do what you want, but 4gs seems way too high. Start with like 2gs or something, tops. You can always take more but never less. Just be safe and don't become the poster child for "don't do drugs" mmkay?
