Does it get worse before getting better? Anxiety medications? (Paroxitine and Clonazepam week 1)

Since taking them my sleep has been a lot more disturbed and I don't feel rested, dizziness increased, acidity increased, constipation increased, loss of appetite, nausea, bloating, easily and frequently triggered due to all this and become anxious or go into a panick attack.

Is this the adjustment period? Does it get worse before getting better?
