whoa, sorry to hear about that Bugma. Can you talk to your Doctor and get a different medication?
Not sure if this will help in your case, but an exercise I used to do to improve transitioning across notes is:
- Sing from the letter E to H, starting slowly and quietly – gradually building volume as you cross from one vowel to the next
- Repeat the exercise, singing from E to H again. Only this time, alternate and change pitch between every vowel
- Repeat the exercise, singing from E to O
- Repeat the exercise, singing from E to O. Again, alternate and change pitch between every vowel.
I hope things get better for you!
