Experiencing Side Effects from Finasteride at 1.25mg Dose

Hi guys I’m 28 and I started Fin 3 weeks ago. I got the 5mg dose but I cut them into quarters (1.25mg). I noticed that my flaccid length has decreased and also that there is no morning wood(I think this happened before starting taking fin. Morning erection was intermittent. Sometimes I get it in the morning and sometimes I don’t before I started fin.). Also I noticed that my libido has dropped but maybe it’s just me over thinking?

My questions are:

Is the smaller flaccid length, no morning wood and low libido a common side effect?

Do side effects occur at 3 weeks?

Should I continue with the 1.25mg?

How can I tackle those side effects?

Let me know if you have follow up questions and ima answer. Thanks in advance.

Let your body adapt to the change, your side effects will disappear, the more you focus on them the more they’re going to manifest, don’t nocebo yourself
