Hello and welcome
Unfortunately you aren’t alone on this one. Just two examples on these links but I’m sure there are many others. @nin certainly managed to work through this and found it a drug worth taking. Sure others have done as well. You may obtain some idea of whether it’s a drug aside effect, which I understand it can be, by the timing. Sometimes it’s difficult. It probably is however best to bear in mind MAV is known to change - we say it morphs - and one way it does this is to move from dizziness to headaches or vice versa so no doubt it can also morph from ‘silent’ to full on classic too.
